Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the name of the fragments that are created on the lagging strand during DNA replication?
A
binding proteins
B
fragmenting lagging strand
C
okazaki fragments
D
coding strands
Explanation: 

Detailed explanation-1: -The discontinuously synthesised fragments are called Okazaki fragments. Okazaki fragments are formed on the lagging strand away from the replication fork and later joined by the enzyme DNA ligase .

Detailed explanation-2: -On the lagging strand, DNA synthesis restarts many times as the helix unwinds, resulting in many short fragments called “Okazaki fragments.” DNA ligase joins the Okazaki fragments together into a single DNA molecule.

Detailed explanation-3: -These are short DNA nucleotide sequences are discontinuously synthesized and further associated by ligase enzyme which gives rise to the lagging strand at the time of DNA replication. They are formed in the lagging strand by the initiation of the creation of a new RNA primer by primo some.

Detailed explanation-4: -Newly synthesized DNA, otherwise known as Okazaki fragments, are bound by DNA ligase, which forms a new strand of DNA. There are two strands that are created when DNA is synthesized.

Detailed explanation-5: -Okazaki fragments are the part of lagging strands. They are short, newly synthesized DNA fragments formed on the lagging template strand during DNA replication. They are complementary to the lagging template strand, together forming short, double-stranded DNA sections.
