How many chromosomes are in each daughter cell at the end of mitosis in a human cell?

• A. 23
• B. 46
• C. 69
• D. 92

Answer: (B)

Verified step by step guidance

1. Understand that mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell.
2. Recall that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent, for a total of 46 chromosomes.
3. During mitosis, the parent cell duplicates its chromosomes, resulting in 92 chromatids, but these are not separate chromosomes yet.
4. The cell then divides through a series of phases: prophase, metaphase, anaphase, and telophase, ensuring each daughter cell receives an identical set of chromosomes.
5. At the end of mitosis, each daughter cell receives 46 chromosomes, maintaining the diploid number characteristic of human somatic cells.
