If given the DNA sequence TTACAGCGTACG on a template strand of DNA, what would be the base sequence of the new strand?
A. CCGTGATACGAA
B. GGCACTATGCTT
C. AATGTCGCATGC
D. AAUGUCGCAUGC

Answer:

C. AATGTCGCATGC is the correct answer.

Explanation:

Starting with the two T's in the beginning, the nucleic base that pairs with thymine (T) is adenine (A). This means that options A and B must be incorrect, since they do not start with two A's.

We've established that T and A are pairs, which means that the correct answer is option C. D is incorrect because it shows uracil (U) instead of thymine. This is the correct pair to adenine in RNA sequences, but this question is referring to the replication of new DNA.
