Biology Question on Molecular Biology
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.
Answer
Enzyme DNA dependent RNA polymerase always catalyse the polymerisation in 5'→3' direction.
Explanation
Solution
The correct answer is (B) : Enzyme DNA dependent RNA polymerase always catalyse the polymerisation in 5'→3' direction.
