Okazaki fragment are seen during A.transcription B.translation C.replication D.transduction?

Question

Answer

The okazaki fragments formed during replication enables the replication of the 3’ 5’ (lagging strand). They are short sequences of DNA nucleotides newly synthesize on the lagging strand. It acts as the building block for the synthesis of DNA in the lagging strand. The fragments are synthesize discontinuously and are later linked together by enzyme DNA ligase to create the lagging strand during DNA replication.

Answer

During replication the irregular replicating DNA strand exhibits Okazaki fragments...

Answer

Replication during the formation of lagging strand

Answer

Okazaki Fragment during Replication

Okazaki fragments are short, newly synthesized DNA fragments that are formed on the lagging strand during DNA replication. These fragments are a result of the discontinuous nature of DNA replication.

Formation of Okazaki Fragments
- During DNA replication, the leading strand is synthesized continuously, while the lagging strand is synthesized in short fragments.
- The lagging strand is oriented in the opposite direction of the replication fork, making it necessary for DNA polymerase to synthesize short fragments in the 5' to 3' direction away from the replication fork.
- These short fragments are Okazaki fragments, typically around 100-200 nucleotides in length in prokaryotes and shorter in eukaryotes.

Role of Okazaki Fragments
- Okazaki fragments are essential for completing the replication of the lagging strand.
- DNA ligase joins the Okazaki fragments together by catalyzing the formation of phosphodiester bonds between the fragments, creating a continuous strand of DNA.

Significance of Okazaki Fragments
- The presence of Okazaki fragments allows for the efficient and accurate replication of the entire DNA molecule.
- Without these fragments, the lagging strand would not be able to replicate properly, leading to errors in the genetic material.

In conclusion, Okazaki fragments are a crucial component of DNA replication, ensuring that both strands of the DNA molecule are accurately and completely replicated.
