Question

Describe the steps involved in synthesis of lagging strand of dna

Answer 1

ANSWER

• The DNA polymerase forms one new strand in a continues stretches in the 5’-3’direction and this is called the leading strand (continuous strand).

• The other new strand is formed in small stretches in the 5’-3’ direction starting from the RNA primer.

• The small fragments are called Okazaki fragments.

• Okazaki fragments are also formed as the enzyme DNA polymerase.

• The okazaki fragments are then joined together to form a new strand by the enzyme DNA ligase.

• This strand is called lagging strand (Discontinues strand).
