Question

Which mRNA sequence is the complement to the DNA sequence GATCAC?

CUAGUG
UAGUGA
AGUGAC
GUGAUC

Answer 1

CUAGUG is the sequence that matches the mRNA sequence and completes the DNA

Answer 2

Normally when a DNA sequence is written, we should define its meaning (5 'and 3') we will consider the DNA sequence as follows: 3 'GATCAC 5'

the RNA sequence should be antiparallel and complementary to that of DNA, so the answer is:

RNA: 5 'CUAGUG 3'
