Use the DNA sequence below to answer the question that
follows.
5' A C A T C G A C G C G C G C A 3
What is the complimentary DNA strand that would result
during replication?
A. 3' U G U A G C U G C G C G C G U5'
It's gonna be answer choice A, because during replication, U (uracil) is used to replace T (thymine) when we're talking about the complimentary strand. Answer A is the only one that has U at the beginning which compliments A (adenine).
