Martha C. Chase was born in Cleveland, Ohio on November 30, 1927. In 1950, she received her bachelor of science from the College of Wooster and then continued schooling at the University of Southern California where she earned her Ph.D. in 1964. She was known for a little in the 1950s, as Martha Epstein since marrying Richard Epstein another scientist, but later divorced. After earning her bachelor degree, she went to the Cold Spring Harbor where she worked as an assistant to Alfred Hershey. Together created the Hershey-Chase experiment called the “blender”. They tested bacteriophage T2 to find out if it was a protein or deoxyribonucleic acid, which passed genetic material down. In order to tell the difference, Hershey and Chase injected protein
with radioactive sulfur and DNA with radioactive phosphorus. They watched virus take place and used a blender that took off the bacteriophage protein coats to distinguish if it was DNA or protein. The virus wasn't radioactive in the protein coat, whereas the virus was radioactive in the deoxyribonucleic acid. Meaning that DNA passes genetic material from the progeny to the F1 generation. With this, they learned how viruses replicate. During May 1952, Hershey published the experiment and included her help that contributes their findings. Martha only stayed there for three years. After that, she was employed at the Oak Ridge National Laboratory with August Doermann. There Doermann, Franklin Stahl, and Martha Chase co-authored papers, including Genetic Recombination and Replication in Bacteriophage. She later moved to work at the University of Rochester. In the late 60s, she became jobless and enrolled, where she seeks out her doctorate degree in microbial physiology from the University of California. She worked at the University of California laboratory until she was diagnosed with dementia. Martha lived in Lorain, Ohio when her life was taken with pneumonia on August 2003. I chose Martha Chase because it was hard for a female to recognized for the work that she assistant Hershey. She didn't receive a Nobel prize, which I believe she should have. Martha worked hard in a laboratory and stood her ground with the men around her. Hershey and Chase made an extremely great impact when they discovered that DNA transferred viruses and that's how we inherit genetic material. With this information helped genetic scientist understand more about deoxyribonucleic acid components and protein. That helped Watson and Crick create the helix model of DNA.

In movies there is always a villain or bad guy to ruin someone’s life or career. The only reason why they go after that person is because of jealously, money, or hatred. It is not always easy for villains or temptresses to get their targets, so they have to come up with clever ideas to lure their victims in. In the movie The Natural Harriet Byrd’s killing spree started off as jealously towards people who are very experienced in what they do and only want fame and fortune from it. When Harriet sees how much potential Roy Hobbs has in playing baseball, she then tries figures out what he wants from his extraordinary talent making him her next victim due to his answer.
It was her cells that became what is known as HELA cells or immortal cells. Her story is interesting to me because of her impact on the science community. Her cells allowed scientist to perform
The history of The Black Civil Rights Movement in the United States is a fascinating account of a group of human beings, forcibly taken from their homeland, brought to a strange new continent, and forced to endure countless inhuman atrocities. Forced into a life of involuntary servitude to white slave owners, African Americans were to face an uphill battle for many years to come. Who would face that battle? To say the fight for black civil rights "was a grassroots movement of ordinary people who accomplished extraordinary things" would be an understatement. Countless people made it their life's work to see the progression of civil rights in America. People like W.E.B. DuBois, Marcus Garvey, A Phillip Randolph, Eleanor Roosevelt, and many others contributed to the fight although it would take ordinary people as well to lead the way in the fight for civil rights. This paper will focus on two people whose intelligence and bravery influenced future generations of civil rights organizers and crusaders. Ida B.Wells and Mary Mcleod Bethune were two African American women whose tenacity and influence would define the term "ordinary to extraordinary".
Ida B. Wells-Barnett dedicated her life to social justice and equality. She devoted her tremendous energies to building the foundations of African-American progress in business, politics, and law. Wells-Barnett was a key participant in the formation of the National Association of Colored Women as well as the National Association for the Advancement of Colored People (NAACP). She spoke eloquently in support of Marcus Garvey and the Universal Negro Improvement Association. The legacies of these organizations have been tremendous and her contribution to each was timely and indespensible. But no cause challenged the courage and integrity of Ida B. Wells-Barnett as much as her battle against mob violence and the terror of lynching at the end of the 19th century.
Martha Euphemia Lofton Haynes was the first African American women to earn a PH.D in mathematics. She was the first and only child of William S. Lofton, a dentist and financier, and Lavinia Day Lofton. Euphemia Lofton Haynes was born Martha Euphemia Lofton on September 11, 1890 in Washington D.C. In 1917 she married her childhood sweetheart Dr.Harold Appo Haynes. They knew each other very well, as they grew up in the same neighborhood when they were teenagers. They both attended, and graduated from M St. High school. Her husband graduated from M St high school in 1906, a year earlier than she did. During their marriage they were highly focused on their careers, and didn’t have any children.
The idea of “family” is almost entirely socially constructed. From grandparents, to friends, to wives and fiancés, the means by which we decide who is related to us and who is not is decided by the person and their milieu. In Mignon R. Moore’s “Independent Women: Equality in African-American Lesbian Relationships”, Eviatar Zerubavel’s Ancestors and Relatives: Genealogy, Identity and Community, and Franz Kafka’s The Judgement, this idea is tested. Who do we consider close enough to us to share our most intimate details and how do we choose them? Each piece offers a different view, which is the “right” way for each of the people described, whether broad (as in Zerbavel’s reading) or specific (as in Moore’s reading), but there are also many similarities in the ways family is defined and actualized.

...or instance, hepatitis C virus), biological molecules (such as cyclic adenosine monophosphate), and Human Immunodeficiency (HIV) virus (Bauman et. al. 2011). Rosalyn had went farther in the world of science than anyone including her self thought was possible (Bauman et. al. 2011). Rosayln and Berson changed history, altered the way science was perceived and their time, and how today we see and research science.
“In the early twentieth century biologists thought that proteins carried genetic information. This was based on the belief that proteins were more complex than DNA.” (The Hershey-Chase "Waring Blender Experiment). It all began when Hershey took a job at the Carnegie Institution of Washington’s Department of Genetics. “He then accepted a position from the Carnegie Institution of Washington 's Department of Genetics at Cold Spring Harbor. Here he and Martha Chase did the Hershey-Chase blender experiment…” (Concept 18 Bacteria and Viruses Have DNA Too). The experiment proved to be effective and its results were groundbreaking. After the experiment Hershey and Chase had their results. “The experiment showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not, confirming that DNA is the hereditary material.” (The Hershey-Chase "Waring Blender Experiment). This was a breakthrough for the field genetics because it ended up influencing many other genetic
Edie Windsor was born in Philadelphia in 1929. She was originally married to a man, but left him in 1950 to move to New York City by herself. Edie received her mathematics degree in 1957 from New York University. She worked in mathematics and computers with IBM. She
Frederick douglas, born in Hale, England in 1879, was a bacteriologist who made the first progressive movement in gaining knowledge related to the structure of DNA. In 1928 he reported one of the first experiments suggesting that bacteria are capable of transferring genetic information via transformation. In his experiment, formally known as Griffith’s experiment, he used two strains of Streptococcus Pneumoniae (pneumococcus) bacteria to infect mice. The two types were type III-S and type II-R. Type III-S had a protective capsule that could shield it from the immune system of the host. In the experiment, bacteria from the type III-S strain were killed with heat and then the remains were added to th II-R strain bacteria. Although neither strain alone was harmful to the mice, the combination was lethal. when looking at the bloodwork of the dead mice. Griffith found live strains of both bacteria. He concluded that type III-S transformed into type II-R. This experiment showed that traits could be transferred from one organism to another. it was one of the first experiments to suggest that DNA was the genetic code because heat denatures protein, thus ruling out the possibility of protein being the genetic code. At this time, DNA was still poorly...
Harriet Manners doesn’t know what to do or say when a modeling agent happens to ask her to model for Yuka Ito - a really famous fashion designer. Harriet knows nothing about fashion, I mean nothing, she once went to school in cat costume. So when she says yes she is whisked off to Russia for her first modeling shoot. Will she be a star or fall out of her sky?
Elizabeth Gilbert was born in Waterbury, Connecticut July 18th, 1969, and grew up on a small farm. She graduated from New york University and graduated with bachelor’s degree in Political Science. She migrated to New York City and began to work as a journalist for Spin, GQ, and New York Times Magazine. Her deteriorating marriage to an ideal American husband formed the beginnings of what would become the travels of her novel, Eat, Pray, Love.
However, it was in high school that she met and later became engaged to a man by the name of Luther Cressman. After attending many high schools because of her family’s travel, she graduated, and was sent to DePauw University at Greencastle Indiana in 1919, where her intention was to major in English. Unfortunately, Margaret was looked down on in DePauw, so she transferred to Barnard College where she studied with Franz Boas and his student Ruth Benedict. It was also at Barnard College that she decided to make anthropology her main field of study. She received her B.A. degree from Barnard in 1923. In September of that same year, Margaret was married to Luther in a small Episcopal Church where she had been baptized. She then continued her studies as a graduate student, and in 1924 she received her M.A. degree in Psychology from Columbia University. In 1925, she completed her doctoral thesis, but did not receive her Ph.D from Columbia until 1929.
Today is a day of hope and of great anticipation. John, my husband, has told me we are to leave to California tomorrow. We are to leave our small, pitiful home here in Massachusetts and find many opportunities in the west. We have heard of many men who have traveled west and discovered gold. “Gold covers California like a blanket,” they have told John. Our farm here leaves no opportunities for our family. Our two sons and three daughters are growing older and we wish for them to be prosperous. Not like now. Now, we have no money and our only value, our farm, is falling apart.
