Dna Extraction Strawberries

Extracting desoxyribonucleic acid from Strawberries Honors 1. why is the grain alcohol phthisis in this lab? Explain its importance and the significance of it being ice greens cold? 5 points The coldness stops the DNA strands from col apart. The DNA strands are held together by hydrogen bonds. When you use love to break the nuclear membrane, the heat can as well break the hydrogen bonds. So you add the cold ethanol to arrest the DNA strands together, and also DNA is non-soluble in ethanol, so it ordain precipitate out. (See Extracting DNA from Strawberries Honors, provided by Ms.Morse, 2/21/12.) 2. Why was the purifying included in the DNA devotee? Molecularly, what advise did it serve? Cite seeds after the answer in APA format. 3 points. The detergent breaks open the jail cell & nuclear membranes. This is because the detergent is a hypotonic solution, which would cause cell lysis. (Wilbraham, A. C. (2005). learner dormitory room chemistry . top(prenominal) Saddle River, N.J.: Prentice Hall.) 3. Would the DNA be the same in any cell in the piece body? Explain. 3 points. Theoretically, yes. All cells are derived from the zygote. However, there can be physical mutations that could change the DNA in random cells. 4.

If DNA was extracted from human beings liver tissue would you follow the same procedure as with strawberries? Explain your answer with a molecular emphasis. 5 points, hurt on sources in APA format after your answer. Strawberries are an nice source for extracting DNA because they are easy to pulverize which breaks the cells of the strawberries apart. The homogenate of strawberries i s produced through and through the energizin! g energy (heat which can weaken or fifty-fifty repose intermolecular forces) mechanically breaking down of the cell paries and structure. (Wilbraham, A. C. (2005). Prentice Hall chemistry. Upper Saddle River, N.J.: Prentice Hall.) 5. In research labs the concentration of DNA in a exemplar is found with a spectrophotometer, explain how this method could testify DNA...If you requisite to get a full essay, order it on our website: OrderEssay.net
