Chromosome count in mitosis
WebAug 8, 2024 · Mitosis contains 4 phases: prophase, metaphase, anaphase, and telophase. In prophase, the nuclear envelope breaks down and chromatin condenses. In metaphase, the chromosomes line up along the metaphase plate, and microtubules attach to the kinetochores of each chromosome. WebThe normal number of chromosomes in a cell is the "diploid" number. In humans, that number is 46 and is sometimes written as 2n. This means the "n" number of …
