Guida verificata passo dopo passo1
Recall the stages of mitosis: prophase, metaphase, anaphase, and telophase, each with distinct chromosomal behaviors.
Understand that chromatin condensation is the process where the loosely packed chromatin fibers coil tightly to form visible chromosomes.
Identify that chromosomes first become visible as distinct, condensed structures during prophase, as chromatin fibers coil and shorten.
Note that in metaphase, chromosomes are fully condensed and aligned at the metaphase plate, but condensation begins earlier in prophase.
Recognize that anaphase and telophase involve separation and decondensation of chromosomes, respectively, so visible condensation starts in prophase.
