Chromosome in anaphase

WebMay 16, 2024 · After DNA replication in the parent cell, each chromosome is composed of two identical sister chromatids. During the anaphase stage of mitosis, these chromatids separate, and one chromatid goes into each … WebIn the fourth step, anaphase, the mitotic spindles pry each chromatid apart from its copy, and drag them to the opposite side of the cell. Four bivalent chromosomes become two groups of 4 monovalent chromosomes. Once anaphase is over, the heavy lifting of …
