Question

FIRST: Only answer if experienced in this field, no counter-questions, "I used to take this but I forgot," or random link-posting.

A triplet of bases in a template strand of DNA is 5' CAG 3'. What would be the corresponding codon for mRNA?

A) 3' GTC 5'
B) 3' GUC 5'
C) 5' GTC 3'
D) 5' GUC 3'

I think it is either answer choice B or C.

Answer 1

*answer choice B or D

Answer 2

So I'm the only AP Bio student/teacher here?

Answer 3

5' CAG '3 is the template strand which is the anti sense strand and thus, the non coding strand. The compliment to that strand is the non template strand which is the sense strand and thus, the coding strand. That strand is 3' GTC '5.

The 3' GTC '5 is what is transcribed into a mRNA transcript 5' CAG '3.
