WebWhen a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA … WebA. only short DNA sequences can extend off the RNA primers. B. DNA polymerase can assemble DNA only in the 5' to 3' direction. C. DNA polymerase can assemble DNA only …
WebMar 7, 2024 · The evolution of the human DNA replication timing program DNA is replicated according to a defined spatiotemporal program that is linked to both gene regulation and genome stability. The evolutionary forces that have shaped replication timing programs in eukaryotic species are largely unknown. WebThe replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine.
WebDNA replication will begin at specific sites called origins of replication where the two DNA strands are separated opening up a replication bubble. At the end of each replication bubble is a replication fork. Which is a Y-shaped region and is the site of active replication.
