WebPrior to S-phase each chromosome is a single chromatin fiber. During S-phase the DNA is replicated and this results in two chromatin fibers (known as sister chromatids). However, these chromatin fibers are attached to each other at the centromere and together they make up a post S-phase chromosome.
WebThe cell goes through 4 steps (prophase, metaphase, anaphase, and telophase.) The cells at the end of the process also have the same amount of chromosomes as the parent cell. At the end, 2 cells are produced. … WebAug 19, 2024 · Both processes involve the division of a diploid cell, or a cell containing two sets of chromosomes (one chromosome donated from each parent). In mitosis, the genetic material ( DNA) in a cell is duplicated and divided equally between two cells. The dividing cell goes through an ordered series of events called the cell cycle.
WebThe cell undergoes a type of cell division called mitosis. In mitosis, two cells called daughter cells are produced, each genetically identical to the parent cell. Learn more …
WebApr 28, 2024 · Mitosis is the step in the cell cycle that the newly duplicated DNA is separated, and two new cells are formed.
