Webreplication is continuous is called the "leading strand.- Leadin½ strand synthesis occurs in the Same direction as movement Ofthe replication fork. The DNA polymerase on the leading strand template has What is high It attaches it not release until it a replication fork moving in the opposite direction, or until the entire strand is replicated WebApr 10, 2024 · A replication fork moves sequentially along the DNA. Replication fork proceeds at about 1000bp/ sec/ fork while okazaki fragment is synthesized every 1 – 2 sec in prokaryotes while the rate of fork movement is slow at ~ 100 bp/ sec/ fork in eukaryotes.

WebD. Nucleotide polymerization occurs only in the 5' to 3' direction Transcription is similar to DNA replication in that A. an RNA transcript is synthesized discontinuously and then pieces are then joined together B. it uses the exact enzyme as that to synthesize RNA primers during DNA replication 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 WebDNA repair process that replaces incorrect nucleotides inserted during DNA replication DNA polymerase. Enzyme that opens the DNA helix by separating the single strands DNA Helicase.
