How does mitosis conserve the chromosome number?

Answer 1

Refer to the explanation.

During the S-phase of interphase, the DNA is replicated, forming two identical sets of DNA. At the beginning of mitosis, the DNA condenses and coils into structures called chromosomes. Each chromosome exists as a pair of identical sister chromatids connected by a centromere.

During metaphase of mitosis, spindle fibers direct the movement of the pairs of sister chromatids to the cell's equatorial plane.

The next phase is anaphase, during which one chromatid from each pair moves to opposite poles of the cell. At this point the chromatids are now individual chromosomes, and there are now two identical sets of chromosomes.

During telophase and cytokinesis, the cell divides into two cells, each with identical sets of chromosomes.

Answer 2

Mitosis conserves the chromosome number by ensuring that each daughter cell receives an identical set of chromosomes to the parent cell. This process involves the replication of the cell's DNA during the S phase of interphase, followed by the segregation of the replicated chromosomes into two identical sets during mitosis. As a result, each daughter cell receives a complete set of chromosomes, maintaining the chromosome number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
