Evolutionary Developmental Biology - Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (Müller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has been exploring the role of the process of individual development and the changes in evolutionary phenotype, meaning the developmental procedure by which single-celled zygotes grow to be multicellular or...   [tags: Biology ] 2219 words

Analysis and Description of Synthetic Biology - Synthetic biology, “the aim is to create improved biological functions to fight current and future challenges”. Like all engineering disciples’ synthetic biology is motivated by application to solve specific problems” (3, 7). “Like chemistry biology is the study of living things. Synthetic biology is replicating and recreating nature, which allows it to sometimes control living things (6). Larger quantities of Artemisinin a drug for malaria will be due to the new E coli strain.

Practical Applications of Evolutionary Biology - Charles Darwin and Alfred Wallace's concept of natural selection and descent with modification helped shape the theory of evolution which holds as much weight as the theory of relativity per se. Evolutionary biology is the science devoted to understanding how populations change through time in response to modifications of their environment and how new species come into being by studying adaptation and diversity (Freeman and Herron 2004). Evolutionary biology has proved that all organisms have evolved from a common ancestor over the last 3.5 billion years....   [tags: Biology] 1498 words

The Utility of Nucleic Acid Hybridisation and Nucleic Acid Probes In Molecular Biology - The unique property of nucleic acids to pair with each other through complementary base pairing is the lifeblood of genetic engineering. A single strand of DNA can pair up with another strand of DNA or RNA if its base pairs are complementary to those of the other strand, under the right conditions of temperature and pH. This phenomenon is called nucleic acid hybridisation. It is possible to exploit this mechanism for the detection of one nucleic acid strand from a mixture of many other strands....   [tags: Molecular Biology]

The Question of Biology is "Why?" - ... Now, we can look at how DNA replication begins. DNA replication begins by unwinding the two DNA strands; an enzyme called helicase accomplishes this. This enzyme uses energy from ATP to unwind the template strand, but like any other process it encounters problems that it must overcome. When DNA is unwound a phenomena called supercoiling can occur—when the DNA is unwound the DNA helix will continue to coil over in space. To overcome this an enzyme called DNA gyrase that helps in relieving the torque that is produced by the unwinding of DNA; this enzyme essentially prevents the helix from supercoiling by changing the topological state of the helix....   [tags: DNA replication, enzymes, polymearse] 1520 words

Conservation Biology in Yellowstone National Park - ... This habitat is home to nearly 60 species of mammals including bison, bears, elk, deer, pronghorn, mountain lions, and wolves. These mammals and many others, along with the parks flora, create the ecosystem that is enjoyed every year by visitors from all over the world. However, due to many political pressures and misconceptions, the ecosystem has been modified due to human impacts. Starting in 1914, the U.S. Congress appropriated funds to be used for the purposes of destroying wolves on public lands in an effort to protect the current elk populations (Frank, 2008)....   [tags: gray, wolf, park, populations, decline] 2126 words

Biology Notes regarding Cells and Related topics - 1. The ability of ice to float because of the expansion of water as it solidifies is an important factor in the fitness of the environment. If ice sank, then eventually all ponds, lakes, and even oceans would freeze solid, making life as we know it impossible on earth. During the summer, only the upper few inches of the ocean would thaw. Instead, when a deep body of water cools, the floating ice insulates the liquid water below, preventing it from freezing and allowing life to exist under the frozen surface....   [tags: Biology Study Tests] 3489 words

Testosterone's Effects on Biology and Behavior - Testosterone's Effects on Biology and Behavior Introduction The study of the interaction between hormones and behavior is truly a complex one. It would be simple if it were true that hormones directly cause a behavior. We know the relationship between hormones and behaviors is reciprocal. Higher levels of hormones increase the probability of certain behaviors, and certain behaviors increase the probability of change in hormones. The Biosocial Model was developed to encompass the influences and relationships the social environment, biology, and behavior have with one another, and how they interact to influence one another....   [tags: Hormones Sexual Behavior Health Essays] 6557 words

Biology - Biology 1. The virus is made up of five parts and is in the size range of 10 nm-300 nm in diameter. The first is the coat made up of protein that protects the virus to a point.

One of these, the influence of nature and nurture on gender roles and behaviors, is argued well by both Deborah Blum and Aaron Devor, both of whom believe that society plays a large role in determining gender. I, however, have a tendency to agree with Blum that biology and society both share responsibility for these behaviors.

Both samples were spun in an ultracentrifuge, in order to isolate the DNA depending on density at maximum speed, and different cycles. The lighter cells were less dense (14N) and stayed close to the top, while the heavy nitrogen sunk to the bottom. When they began with heavy nitrogen, the bacteria made copies of themselves, and then their DNA split in the middle making two DNA strands....   [tags: studying DNA formation] 718 words

Molecular Biology is the Transcription from DNA to RNA - ... In this experiment, if done correctly, there should be 314 base pairs of beta-actin (housekeeping gene) and 480 base pairs of MMP-9. Beta-actin is run as a control since it is always present and is constantly produced within cells. MMP-9 is a gene that is used to digest extracellular matrix proteins. It does not become active until it is excreted out of the nucleus. In order to produce MMP-9 through the treatment of PMA via signal transduction, a signal is triggered through receptors in the cell’s membrane to a secondary messenger, PKC-beta, which in turn induces a response in DNA for a cell to modify and produce an end product, MMP-9 (Lab Manual, 2014)....   [tags: polymerase chain reaction. cells, students] 1089 words
