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 $5'AUCGAUCGAUCGAUCGAUCGAUCG\,AUCG 3'$?
A
$3' ATCGATCGATCGATCGATCGATCGATCG 5'$
B
$5' UAGCUAGCUAGCUAGCUAGCUAGCUAGC 3'$
C
$3' UAGCUAGCUAGCUAGCUAGCUAGCUAGC 5'$
D
$5'ATCGATCGATCGATCGATCGATCGATCG 3 '$
(NEET-2023)
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 $3 '$
