5.Molecular Basis of Inheritance
medium

Which one of the following is the sequence on corresponding coding strand, if the sequence on mRNA formed is as follows $5'AUCGAUCGAUCGAUCGAUCGAUCG\,AUCG 3'$?

Solution

The sequence of coding strand is same as RNA except thymine at the place of uracil.

Template strand $\rightarrow$ 3'-TAGCTAGCTAGCTAGCTAGCTAGCTAGC-5'

Coding strand $\rightarrow$ 5'-ATCGATCGATCG ATCGATCGATCGATCG-3'

$\downarrow$ Transcription

mRNA $\rightarrow$ 5' AUCGAUCGAUCGAUCGAUCGAUCG AUCG $3 '$
