Question

What do you mean by Okazaki fragments?

Answer 1

Okazaki fragments:

1. The discontinuous short sequences of DNA nucleotides are known as Okazaki fragments.
2. The formation of Okazaki fragments occurs during the process of DNA replication to synthesize the lagging strand of DNA.
3. As the process of DNA replication in eukaryotes and prokaryotes is different, the Okazaki fragments are shorter in eukaryotes and longer in prokaryotes.
4. The size of Okazaki fragments ranges from 150-200 base pairs in eukaryotes while 1000-2000 base pairs in prokaryotes.
5. The Okazaki fragments are joined by the enzyme DNA ligase.
