Homework Answers
Answer
Sample 1 is human DNA.Because as per Chargaff's rule in a double stranded DNA the number of purines is equal to number of pyrimidines( ie amount of guanine=cytosine and amount of adenine=thymine).Sample 1 satisfies this rule.
Sample 2 is single stranded RNA of corona virus because in RNA uracil is present instead of thymine.In sample 2 we can see that amount of thymine is zero.
Sample 3 is single stranded DNA of phi x 174.Because in ssDNA there is no Chargaff's rule.

1 Overview and Background Many of the assignments in this course will introduce you to topics in computational biology. You do not need to know anything about biology to do these assignments other than what is contained in the description itself. The objective of each assignment is for you to acquire certain particular skills or knowledge, and the choice of topic is independent of that objective. Sometimes the topics will be related to computational problems in biology, chemistry, or physics,...
