Question

1. challenge: human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. once the chromosome has split, each chromatid is called a daughter chromosome. at the end of cytokinesis, how many daughter chromosomes will be found in each cell? explain. 46 because

Explanation:

During mitosis, the parent cell (with 46 chromosomes) replicates its DNA. Each chromosome (with two chromatids) splits at the centromere. The sister chromatids (now daughter chromosomes) are pulled to opposite poles of the cell. Cytokinesis divides the cytoplasm, resulting in two daughter cells. Each daughter cell receives an identical set of chromosomes to maintain the diploid number (46 in humans). This ensures genetic consistency between the parent and daughter cells.

Answer:

46 because during mitosis, the parent cell replicates its DNA. Each chromosome splits at the centromere, and sister chromatids (daughter chromosomes) are distributed equally. Cytokinesis forms two daughter cells, each inheriting the diploid number (46) to maintain genetic consistency.
