mRNA is synthesised on DNA template in which direction : -
A 5' $\rightarrow$ 3'
B 3' $\rightarrow$ 5'
C Both
D Any

Detailed Solution

RNA polymerase can add nucleotides only to the free 3'-OH end of the growing chain.
So the new mRNA is always synthesised in the 5' $\rightarrow$ 3' direction (the template strand is read 3' $\rightarrow$ 5').
So mRNA is synthesised in the 5' $\rightarrow$ 3' direction.
