The anticodon of yeast serine tRNA is 5' AGC 3' which of the following is most likely to be serine codon?

A) 5' ACG 3'
B) 5' CGG 3'
C) 5' GCU 3'
D) 5' UAG 3'
E) 5' UCG 3'

the ans is either C or E . am usually so confuse on where to read from

Answer is C

You have to go antiparallel to get the mRNA codon.
So starts from the 3' end and look for "U" as it complements the the "A" in the anticodon. The only option is here is C which is 5' CGU 3'

yep guys C is the write answer

we always write from 5' onwards... and 5' base pairs with 3' end...
