Question

What will be the complementary RNA sequence for the following DNA sequence?
5' AATGCCTTAAGC 3'

• A. 5' GCUUAAGGCAUU 3'
• B. 5' UUACGGAATTCG 3'
• C. 3' UUACGGAAUUCG 5'
• D. 3' AAUGCCUUAUCG 5'
• E. 5' UUACCGAUUUCG 3'

Answer 1

The correct option is C 3' UUACGGAAUUCG 5'

In RNA, uracil is a unique base, whereas in DNA, thymine is the unique base. Strands run antiparallel; one strand runs from 5' --->3' and other strand runs from 3' ---->5' direction. The DNA sequence given is : 5' AATGCCTTAAGC 3'.
The complementary RNA strand is 3' UUACGGAAUUCG 5'.
