2. A. B. C. The DNA of each species has a different base composition. Find the base composition of each species, using what you know about complementary base pairing. Human DNA is approximately 20% C. G=% A = % T= % In the bacteriophage DX174, the DNA is approximately 26% A. G= % T= % Sea urchin DNA is approximately 18% G. C = % C = % A = % T = %

8a. Given the following mutated sequence (with respect to the normal sequence), what TYPE of mutation occurred: AAACGTTAC 8b. Where did the mutation take place?

1. Compare the sugar-phosphate arrangement in the backbone of the DNA from the plant, the mammal and the bacterium. Are there any differences? 2. Which bases are present in the DNA of the plant? The mammal? The bacterium? Are the same bases present in all three cases? Are the bases in the same order?

DNA Polymerase Holoenzyme IIlI is represented below. It consists of several domains with distinct functions. The structure capable of 5' to 3' DNA polymerization is represented by the letter and the structure capable of 3' to 5' exonuclease activity is represented by the letter B. -D DNA Pol II holoenzyme D; A А; С А;B А А; D В; D O O

DNA Polymerase Holoenzyme Ill is represented below. It consists of several domains with distinct functions. The structure that provides high processivity (processivity factor) is represented by the letter and the structure that provides DNA proofreading function is represented by the letter A В. -C -D DNA Pol III holoenzyme В; D А; А А; D D; A A; C

I don't understand my homework. I struggled how to slove the problem DNA-DNA complementary base pairing. I don't get it at all. Can you help me to explain to me, please?

35. M Heinz Shuster collected the following data on the base composition Move ANALYSIS ribgrass mosaic virus (H. Shuster, in The Nucleic Acids: Chemistry and Biology, vol. 3, E. Chargaff and J. N. Davidson, Eds. New York: Academic Press, 1955). On the basis of this information, is the hereditary information of the ribgrass mosaic virus RNA or DNA? Is it likely to be single stranded or double stranded? Percentage A T U Ribgrass 29.3 25.8 18.0 0.0 27.0 mosaic virus Leibniz Institute for Age Research, Fritz Lipmann-Institute. Ribgrass mosaic virus.

see the attached multiple choice question. thank you
