What happens during anaphase of mitosis and anaphase II of meiosis?
In anaphase of mitosis (and meiosis II), cohesin protein holding the centromeres of the sister chromatids together is cleaved, allowing the sister chromatids to segregate to opposite poles of the cell, at which point they are called chromosomes.
How is what occurs during anaphase II of meiosis II more similar to mitosis than meiosis I?
Meiosis II is much more similar to a mitotic division. … During anaphase II and mitotic anaphase, the kinetochores divide and sister chromatids, now referred to as chromosomes, are pulled to opposite poles. The two daughter cells of mitosis, however, are identical, unlike the daughter cells produced by meiosis.
What event occurs in both meiosis and mitosis?
Which of the following occur in both mitosis and meiosis? Explanation: The separation of sister chromatids is the only item of the answer choices that occurs in both mitosis and meiosis. Prophase II and metaphase II only occur in meiosis, as does recombination between homologous chromosomes.
Which event takes place during anaphase 2?
In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.
How does segregation happen during anaphase 2?
There are two ways in which non-disjunction can occur: 1) both homologous chromosomes migrate together to one pole instead of separating to opposite poles in Anaphase I or 2) sister chromatids fail to separate properly and both sister chromatids move together to one pole instead of to opposite poles in Anaphase II.
In what ways is meiosis II similar to and different from mitosis of a diploid cell?
The mechanics of meiosis II are similar to mitosis, except that each dividing cell has only one set of homologous chromosomes, each with two chromatids. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
How are mitosis and meiosis similar and different?
Mitosis has only one round of cell division, while meiosis has two. … Mitosis produces daughter cells (diploid cells) that are identical to the parent cell, while mitosis produces haploid/monoploid cells that only have half of the normal number of chromosomes.
What occurs in both mitosis and meiosis quizlet?
Both mitosis and meiosis are associated with cytokinesis. The end result of both are daughter cells produced from a parent cell. The fundamental sequence of events in mitosis is the same as in meiosis (in meiosis it happens twice).
What function is common to both mitosis and meiosis in humans?
Mitosis and meiosis both represent cell division that occur in humans and other animals. These cell division processes share many aspects, including the production of new cells and replication of genetic material.
Do both mitosis and meiosis require DNA replication?
Yes, DNA replicates in both mitosis and meiosis. In meiosis, the cell undergoes two divisions, i.e. meiosis I and II. Meiosis I is reduction division and meiosis II is similar to mitosis but DNA replicates only once during meiosis, i.e. before meiosis I in S phase.
