Question

What is the purpose of DNA polymerase? A) It carries genetic information to the ribosomes. B) It produces a complementary copy of a strand of DNA. C) It constructs RNA chains using a template from DNA genes. D) It retrieves amino acids from the cytoplasm for protein construction.

Answer 1

B It helps in DNA Replication'

Answer 2

The correct answer would be B) It produces a complimentary copy of a strand of DNA.

DNA polymerase is an enzyme that catalyzes the polymerization of deoxyribonucleotides.

It helps in the synthesis or replication of DNA by producing the complimentary copy of a strand of DNA.

It requires RNA primer to initiate the replication process as it can add nucleotide only in 3' to 5' direction.

The overall chemical reaction can be written as:

`DNA_(n) + deoxynucleoside triphosphate` ⇄
`DNA_(n+1) + diphosphate`
