DNA REPLICATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following enzymes is responsible for synthesizing the new DNA strand?
A
DNA polymerase
B
Helicase
C
Primase
D
DNA ligase
Explanation: 

Detailed explanation-1: -The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain. However, DNA replication is much more complex than a single enzymatic reaction.

Detailed explanation-2: -DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules.

Detailed explanation-3: -The main function of the DNA polymerase is to synthesize DNA by the process of replication. It is an important process to maintain and transfer genetic information from one generation to another. DNA polymerase works in pairs, replicating two strands of DNA in tandem.

Detailed explanation-4: -RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
