Lagging and leading strand dna replication
WebWhen DNA is being copied, one of the two new strands of DNA at a replication fork is made continuously and is called the leading strand. The other strand is produced in many small pieces called Okazaki fragments, each of which begins with its own RNA primer, and is known as the lagging strand. (See the article on DNA replication for more details.) WebNov 27, 2024 · The lagging strand is a single DNA strand that, during DNA replication, is replicated in the 5′ – 3′ direction (opposite direction to the replication fork). DNA is added to the lagging strand in discontinuous chunks called ‘okazaki fragments’. What is the purpose of the Okazaki fragments?
Lagging and leading strand dna replication
Did you know?
WebWhile the DNA polymerase proceeds, leading strand can track the replication fork, as DNA polymerase moves towards 5' to 3' direction, in the lagging strand, the enzyme has to … Web1. During DNA replication, the leading strand is synthesized continuously, while the lagging strand is synthesized as Okazaki fragments. This is because: a. DNA synthesis can take place only in the '5--->3' direction b. DNA polymerases can bind to only one strand at a time
WebReplication of the lagging strand is discontinuous. Replication of the leading strand is continuous. Replication of the leading strand begins near the origin of replication. Replication of the lagging strand occurs in fragments as the original DNA is unwound. DNA polymerase fills in gaps in the lagging strand. WebExplanation: the lagging strand,on the other hand,is replicated discontinuously because its template strand is oriented in the opposite direction of the replication fork movement.therefore, the DNA polymerase has to move backward,creating short DNA fragments (Okazaki fragments) that are later joined together by DNA ligase
