1. The problem statement, all variables and given/known data Background Erwin Chargaff discovered that although the nucleotide composition of DNA varies from one species to another,that composition always follows certain rules. While the variation in nucleotides helps to explain the complexity of life, the physical structure of the DNA itself can also help certain organisms adapt to particular environments. Imagine you are working with a research team sampling the ocean floor near a hot vent that releases a steady stream of hot water. The hot water has a temperature of about 45°C, while the surrounding ocean has a temperature of 6°C. Your team collects two samples of bacteria — one from the mouth of the hot vent, and one from the ocean floor about 20 m away. When you return to the lab, you isolate the DNA from these bacteria to determine their nucleotide composition. The table shows the results of your test for the adenine content of the DNA. Apply what you have learned about Chargaff’s findings and DNA composition to solve the following problems. 1. Complete the table to determine the amounts of the other nucleotides found in each DNA sample. 2. For each DNA sample, draw a linear stretch of DNA about 15 nucleotides long, with a nucleotide composition that corresponds to its data set. With a dotted line, illustrate the hydrogen bonds between complementary base pairs. 3. Considering the bonds between base pairs, which of these DNA samples is most likely taken from the bacteria collected at the mouth of the hot vent? Explain your answer. I filled out the stuff in the red 2. The attempt at a solution I have a hard time doing the second question, which is to draw the thing, can you please help me, i try to then i get decimal stuff to draw such as since adenine is 31%, thus (.31)(30) = 9.3 how can i draw .3 of adenine. or am i doing something wrong, please help me with the second and the third question. i got this assignment due tomorrow Please help, i would really appreciate it. Please help, its due tomorrow. Thank you so much.
