What is the funcional of the enzyme DNA polymerase in replication?

A) It reads the sequence of nucleotides on the parental strand of DNA and catalyzes the polymerization of a complementary daughter DNA strand.

B) Its reads codond on a DNA molecule and catalyzes the polymerization of a complementary mRNA strand,

C) It unwinds the double helix of DNA and separetes the two strand.

D) It connects the short Okazaki fragments formed in the lagging strand.

E) It carries the amino acid that are necessary to form a new daugther strand.

Homework Answers

Answer #1

Answer is option (a) it reads the sequence of nucleotides on the parental strand of DNA and catalyzes the polymerization of a complementary daughter DNA strand.

Explanation

DNA replication is the process of producing 2 identical copies of a DNA.
Steps of DNA replication involves

1. Unwinding of double helix into 2 strands by the help of enzyme helicase and formation of replication fork.

2. DNA polymerase enzyme adds nucleotides to one strand of DNA

3. Ligase enzyme connect okazaki fragments together

4. Topoisomerase enzyme cuts and rejoin the helix

5. RNA primase enzyme synthesize RNA primer molecules

DNA polymerases are multi-subunit enzymes which catalyzes the addition of nucleotides into the existing strand of DNA.
