WebA. When cells are duplicated, there is transfer of DNA or genetic information from the parent cell to the daughter cells. So for this transfer to be made possible and to ensure equal … WebSep 27, 2024 · DNA replication is the process by which cells make a copy of their DNA before cell division. DNA replication is a semi-conservative process, meaning that one strand of the original DNA molecule serves as a template for the synthesis of a new complementary strand. DNA replication is initiated at specific sites called origin of …
WebDNA is replicated prior to meiosis I but not before meiosis II. Meiosis i produces two haploid cells. Meiosis Il produces four haploid daughter cells.

WebAug 24, 2024 · The second phase is the S phase, in which DNA is replicated in order to form two sets of chromosomes. In the third phase, another gap phase called G2, other cellular material is replicated. The fourth phase is mitosis, in which the chromosomes are segregated and the cell splits into two. phis2.1WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a … tspot loginWebIf DNA replication occurred again before meiosis II, the sister chromatids would be replicated and the cells would have four copies of 23 individual chromosomes. At the end of meiosis II, the resulting haploid cell would have two copies of 23 individual chromosomes, a condition that is incompatible with life. phis2.1 载体图谱WebDNA is replicated before cell division, so the same genetic material can pass from parent to offspring.
