Please Answer ALL questions. Thanks!
5) Imagine you have discovered a new species of amoeba. To begin your investigation of this organism. you run an assay on the total nucleotide content of the bacterial cells. If 22 percent of the nucleotides in the DNA are cytosine, what percentage of the DNA is made of adenine nucleotides? Show your work. 2 6) Imagine that you are an interior architecture/biology double-major. While at home during break, one of your friends asks you to design and help build a spiral staircase that is modeled after a DNA molecule. The staircase must have 12 steps and each step needs to be 6-feet wide. You say, "OK, as long as you provide the materials." Then your friend shows you what you have to work with: two spiral railings with an 18° twist and some boards. The trouble is the only boards he has for you to work with are either 2-feet long or 4-feet long. Explain why you are still able to design and build the staircase using the materials he has on hand. What features of DNA will be modeled by the stair?Explanation / Answer
5.According to the chargaff rule,Amount of purine is equal to pyrimidine .(A+G)=(C+T). It means if cytosine is 22% them guanine is also 22% and then adenine and thymine is 78% .
6.DNA is a double helix structure and can be designed as a staircase in which supercoiling of base pair are arranged on an axis.This doble helical supercoiling is most important feature for arranged in a staircase.
