Web43. Explain why half of DNA is replicated in a discontinuous fashion. Replication of the lagging strand occurs in the direction away from the replication fork in short stretches of DNA, since access to the DNA is always from the 5’ end. This results in pieces of DNA being replicated in a discontinuous fashion. WebApr 11, 2024 · The two-cycle engine described above is an almost failsafe way to prevent genotoxic over-replication.

WebWhat is a restriction enzyme? a) enzymes that bind to DNA polymerase molecules to prevent DNA from being replicated. b) enzymes that dissociate proteins in the nuclear envelope after mRNA strands exit the nucleus. c) bacterial enzymes that regulate levels of mitosis‑promoting factor to limit the rate of cell division. WebThe phage DNA is replicated and transcribed in a coordinated manner, with early genes being expressed first, followed by middle and late genes. The early genes are involved in phage DNA replication and transcription, while the middle and late genes are involved in the assembly of new phage particles. The phage proteins are synthesized using the ... knock two times on the ceilingWebThe process is quite rapid and occurs with few errors. DNA replication uses a large number of proteins and enzymes ( Table 11.1 ). One of the key players is the enzyme DNA polymerase, also known as DNA pol. In bacteria, three main types of DNA polymerases are known: DNA pol I, DNA pol II, and DNA pol III. knock two times

"WebDec 16, 2024 · In cycling cells with depleted CHK1 gene, premature mitotic entry was observed when mildly under-replicated DNA occurred at the end of the S-phase [90,91]. This was due to a low threshold of origin firing . In this way, unfinished replication can continue during the G2 phase and during G2/M transition, but with a lower intensity … " - Dna being replicated
