Question

A particular triplet of bases in the template strand of dna is 5′-agt-3′. What would be the corresponding codon for the mrna that is transcribed? A. 3 UCA 5 B. 3 UGA 5. C. 5 TCA 3 D. 3 ACU 5

Answer 1

Answer:

3 UCA 5

Explanation:

The 5' end of a strand pairs up with the 3' of its complimentary strand. So with this fact, we can rule out option C.

Now when you pair the DNA template with the mRNA template, remember that RNA contains uracil and not thymine. So the base pairings would be:

T = A

A = U

U = A

G = C

C = G

Based on this, the pairing would be like this:

5' A G T 3'

3' U C A 5'
