What are Okazaki fragments?
|
|
Sections of RNA removed by DNA polymerase III and replaced with DNA
|
|
|
Nucleotides added by DNA polymerase I in the same direction as the replication fork
|
|
|
Short sections of DNA formed during DNA replication
|
|
|
Short lengths of RNA primase attached to the DNA during replication
|
Explanation:
Detailed explanation-1: -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-2: -Answer and Explanation: Okazaki fragments are produced because the DNA polymerase can only synthesize in the 5’ to 3’ direction. Recall that DNA consists of two complementary strands that are antiparallel in arrangement.
