1. The purpose of mashing up the strawberry in the beginning was to break down the cell wall and admit the contents of the cell to be release. This allows for us to get closer to the DNA within the cell, although the membranes are still obstacles.
2. We mushed the strawberry with salty solution so that the cells would lyse. The salt releases the DNA strands by breaking up the protein chains that hold the nucleic acid together. DNA is soluble in salt but not in salt water, while all other contents of the cell are soluble in both. Because of this, when the DNA encounters salt water, it parts from the other contents of the cell and stays together.

This Cherokee folktale tells the story of the first man and woman on Earth. They were married and lived happily together for a long time. One day, they quarreled and the woman left. The man followed her to apologize, but the woman walked so fast that he could not catch her. It was then that, seeing his frustration, the Sun decided to help him. In an effort to slow her down, the Sun made different berries appear in front of the woman, but she paid not attention to them. It wasn't until she saw the strawberries that she decided to stop. The husband finally caught up with her and apologize.
These six samples (crude -/+, broken -/+, and whole -/+) were spun at 5000 rpm, and the resulting pellets were isolated and resuspended in DNase buffer. The set of suspensions labeled with a (+) was incubated in DNase enzyme for 15 minutes, and afterwards incubated in 15 uL of STOP solution. All six samples were lysed for DNA extraction with DNA extraction buffer, and micro-centrifuged at maximum speed. To precipitate the extracted DNA, the supernatants from each of the six samples were added to their correspondingly labeled micro-centrifuge tubes containing 7% ethanol (Parent et. al, 2008To bind the DNA, the ethanol lysate mixtures were transferred to labeled spin columns and spun for one minute in the micro-centrifuge at maximum speed. To wash the bound DNA, the spin columns were washed and spun three times at maximum speed. In order to elute the bound DNA, the samples were washed in 80 uL of distilled water and spun again for 2 minutes at maximum speed (Parent et. al,
Osmosis Experiment Planning Aim: The main subject that I will be planning to investigate is the effects of a concentrated sucrose solution on potato cells on the basis of the Osmosis theory. Background knowledge: The plant cell and its structure To understand osmosis in detail I will need to explain the plant cell (which is the cell included in the osmosis experiment) and its cell membrane. Below I have a diagram of a plant cell: [IMAGE] Osmosis is about the movement of particles from a higher concentrated solution to a lower concentrated solution to create an ethical balance via a partially or semi permeable cell membrane. Osmosis in simple terms is the exchange of particles between the cytoplasm inside the cell and the solution outside the cell. What makes this exhange is the partially permable cell membrane.
Osmosis in Carrots Background Osmosis is the diffusion of water from a dilute solution to a more concentrated solution through a partially permeable membrane, which allows the pass of water molecules but not solute molecules. [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE]If a cell is placed in a less concentrated solution water enters because the less concentrated solution will have a high concentration of water than the inside of the cell. Once the cell takes in maximum water the cell becomes turgid. If the cell was to be placed in a high concentrated solution, water would leave the cell because the cell would contain a low concentrated solution. So in the low concentrated solution there will be a high concentration of water and in the high concentrated solution there will be a low concentration of water.
The. So if there is a lot of salt dissolved into water surrounding the organism (in this case a potato chip) then water particles from. other cells are going to attempt to equal the concentration of water. in the solution with the water concentration in the cell. Therefore most of the water from the cells of the potato chipping will change in mass, depending on the concentration of solution.
Each of the nucleotides accommodate a phosphate group, sugar group, and a nitrogen base. There is four nitrogen bases in DNA. The four nitrogen bases are; Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Each of the bases are connected to a sugar molecule and a phosphate molecule. They are then positioned into two long strands that form a spiral called a double helix (DNA). The nitrogen bases are paired up with one another. Adenine and Thymine will always be paired with each other because of the bonds between them. Between A and T, there are two hydrogen bonds. The same goes with Guanine always being paired with Cytosine due. Between both G and C there is three hydrogen bonds. The nitrogen bases Adenine and Guanine won’t pair up with each other because, of their size. Both the nitrogen bases Adenine and Guanine are a purine base. Thymine and Cytosine are both a pyrimidine base. Adenine pairs with Thymine, and Guanine pairs with Cytosine, because they are of opposite
The Reasoning behind the experiment is to see what effects Temperature has on the permeability of Phospholipid bi-layer of Beetroot cells and the amount of pigment released from the vacuole.
Ingmar Bergman’s Wild Strawberries, while released in 1957, embodies a refreshingly progressive perspective in its portrayal of women. Undoubtedly, Wild Strawberries is Isak Borg’s journey, both literal and spiritual, of realization, recollection, and redemption. However, its female characters, namely Marianne and the Sarahs of both generations, play an integral part in Isak’s transformation. Other movies we viewed from this era, specifically Au Hasard Balthazar and La Strada, tended towards victimization of female characters, from sexual assault to unhealthy dependencies. However, Wild Strawberries shies away simultaneously from those trope and the feminist stereotype of bra-burning, man-hating liberationism. Marianne, in particular, functions

Cells are of two distinctly different types, prokaryotes and eukaryotes; thus, the living world is divided into two broad categories. The DNA of prokaryotes is a single molecule in direct contact with the cell cytoplasm, whereas the DNA of eukaryotes is much greater in amount and diversity and is contained within a nucleus separated from the cell cytoplasm by a membranous nuclear envelope. Many eukaryotic cells are further divided into compartments by internal membranes in addition to the nuclear envelope, whereas prokaryotic cells never contain completely
