Humans have 23 pairs of chromosomes. During mitotic cell division, sister chromatids get separated to opposite sides of the cell (during anaphase). resulting in two sets of identical chromosomes. The cell divides, becoming two distinct cells, each with their own nucleus. Usually mitosis occurs with no problems, however, there have been cases where the chromatids do not separate properly. If the sister chromatids do not separate during anaphase, what would the two resulting nuclei look like? How many chromosomes would be in each of the resulting nuclei, assuming this is a human cell?

Text Solution

AI Generated Solution

To answer the question about what happens if sister chromatids do not separate properly during anaphase in a human cell, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Chromosome Number**: - Humans have a total of 46 chromosomes, which are organized into 23 pairs. Each pair consists of one chromosome from the mother and one from the father. 2. **Normal Mitosis Process**: ...
