Q. Select the correct option. Direction of RNA synthesis Direction of reading of the template DNA strand
A) 5′ – 3′ 3′ – 5′
B) 3′ – 5′ 5′ – 3′
C) 5′ – 3′ 5′ – 3′
D) 3′ – 5′ 3′ – 5′
Explanation
RNA polymerase initiates and extends the RNA (chain elongation) and functions always in 5′ to 3′ direction. The structural component of DNA has 3′ to 5′ polarity. It is also called template DNA strand or antisense (–) strand.
