Question
During DNA analysis, a sample of double-stranded DNA has 62% GC. What is the percent of adenine (A) present in the DNA sample?
Correct Answer
Option C is the correct answer.
Detailed Explanation
If GC content is 62%, then the AT content is 100% - 62% = 38%. Since A and T are equal, A = T = 38%/2 = 19%. Therefore, adenine makes up 19% of the bases.
Hint
What's the relationship between G+C and A+T? And between A and T?
