Two chromatids are joined in the middle by
Web– During metaphase, chromosomes line up in the middle of the cell. Anaphase is characterized by three events: 1. Centromeres that join the sister chromatids split. 2. Sister chromatids separate becoming individual chromatids. 3. Separated chromatids move to opposite poles of the cell. • Mitosis divides the cell’s nucleus in four phases. Web1 Centromere attaching the two chromatids divides/splits. 2 The two sister chromatids of each chromosome separate and are drawn apart towards opposite poles pulled by shortening of spindle fibres. 3 A furrow starts in the cell membrane at the middle in the animal cell. 4. Name and explain the various stages of the cell cycle. Solution:-

WebImage of crossing over. Two homologous chromosomes carry different versions of three genes. One has the A, B, and C versions, while the other has the a, b, and c versions. A crossover event in which two chromatids—one from each homologue—exchange fragments swaps the C and c genes. Now, each homologue has two dissimilar chromatids. WebCentromere - chromosomes replicate, becoming two identical linear DNA molecules. The two DNA molecules are held together at a region (on each molecule) called the centromere.Throughout mitosis, until the centromeres separate Spindle fibers - Spindle fibers attach to centromeres and pull sister chromatids to the center of the cell spindle is …
