WebFirst thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. ... the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome ... WebDuring the S-phase of interphase, the DNA is replicated, forming two identical sets of DNA. At the beginning of mitosis, the DNA condenses and coils into structures called chromosomes.Each chromosome exists as a pair of identical sister chromatids connected by a centromere.

WebThe duplicated chromosomes align on a second spindle, and the sister chromatids separate to produce cells with a haploidDNA content. Meiosis thus consists of a single phase of DNA replication followed by two cell divisions. Four haploid cells are therefore produced from each cell that enters meiosis. Meiosis and mitosisare compared in …

WebApr 9, 2024 · When the cell enters S-phase in the cell cycle (G1-S-G2-M) all the chromosomal DNA is replicated. This is done by enzymes called DNA polymerases. All DNA polymerases synthesize new strands by adding nucleotides to the 3'OH group present on the previous nucleotide.
