WebThe process of mitosis, or cell division, is also known as the M phase. This is where the cell divides its previously-copied DNA and cytoplasm to make two new, identical daughter … WebTelophase (the “distance phase”): the chromosomes reach the opposite poles and begin to decondense (unravel), relaxing once again into a stretched-out chromatin configuration. The mitotic spindles are depolymerized into tubulin monomers that will be used to assemble cytoskeletal components for each daughter cell.

WebIn meiosis 1, the number of chromosomes is reduced by one-half and for this reason, it is called reduction division. Meiosis 2 results in separation the sister chromatids and for this reason, it is known as equatorial division. … WebThe cell cycle is an orderly sequence of events. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages. In eukaryotes, the cell cycle consists of a long preparatory period, called interphase.

Chromosome condensation and decondensation during mitosis

Web15 apr. 2024 · Chromosomes are most compacted (condensed) when lining up in metaphase and dividing in telophase to keep DNA molecules intact. Understanding Key Concepts The sequence of bases in a strand … WebIn the S phase, the DNA of the chromosomes is replicated. Finally, in the G 2 phase, the cell undergoes the final preparations for meiosis. During DNA duplication of the S phase, each chromosome becomes composed of two identical copies (called sister chromatids) that are held together at the centromere until they are pulled apart during meiosis II.
