WebJan 23, 2024 · Definition: Sister chromatids are two identical copies of a single replicated chromosome that are connected by a centromere. Chromosome replication takes place during interphase of the cell cycle. DNA is synthesized during the S phase or synthesis phase of interphase to ensure that each cell ends up with the correct number of … WebApr 13, 2024 · During mitosis in eukaryotic cells, mechanical forces generated by the mitotic spindle pull the sister chromatids into the nascent daughter cells. How do mitotic chromosomes achieve the necessary mechanical stiffness and stability to maintain their integrity under these forces? Here, we use optical tweezers to show that ions involved in …

WebThe mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis. Prophase II. If the chromosomes decondensed in telophase I, they condense again. Webchromosomes has its own unique set of genes. For example, chromosome 11 has the genes shown in question 2. There are over 1000 additional genes on chromosome 11. In this activity, you will use model chromosomes that represent chromosome 11 and chromosome 4. Chromosome 4 has over 1000 genes, including a gene that can result …
