Molecular Basis of Inheritance

During transcription the DNA strand with 3’ → 5' polarity of the structural gene always acts as a template because

A
Nucleotides of DNA strand with 5' → 3' are transferred to mRNA
B
Enzyme DNA dependent RNA polymerase always catalyse the polymerisation in 5’ → 3' direction
C
Enzyme DNA dependent RNA polymerase always catalyse the polymerisation in 3' → 5' direction
D
Enzyme DNA dependent RNA polymerase always catalyse polymerisation in both the directions

Solution:

B. Enzyme DNA dependent RNA polymerase always catalyse the polymerisation in 5’ → 3' direction
