Question

Meiosis II is similar to mitosis in that

1. sister chromatids separate during anaphase
2. DNA replicates before the division.
3. the daughter cells are diploid.
4. homologous chromosomes synapse

Short answer

1. The option “sister chromatids separate during anaphase” is true.
2. The option “DNA replicates before the division” isfalse.
3. The option “the daughter cells are diploid.” is false.
4. The option “homologous chromosomes synapse” is false.

Step-by-step solution

Description of meiosis

There are two types of cell division, namely, mitosis and meiosis. Meiosis is the process that is specific for the sex cells. In meiosis, the division of cells takes place twice to form four haploid daughter cells.

Explanation of option “(A)”                                                           

Anaphase is a similar phase in mitosis and meiosis II. In this process, the cohesion protein is removed from the sister chromatids to allow the movement of the sister chromatids.

The segregation phase of chromosomes takes place in the anaphase of both mitosis and meiosis II.

Therefore, the given option is true.

Explanation of option “(B)”

Meiosis II is the process in which DNA replication occurs at the starting of meiosis II. The replication of DNA does not occur at the end of meiosis since there is no interphase required in the meiotic phase.

Mitosis is the process in which DNA replication takes place in the interphase or synthesis phase.

DNA replication is the difference between mitosis and meiosis II.

Therefore, the given option is false.

Explanation of option “(C)”

The daughter cells produced in the meiosis II process are haploid. The mitosis process can form both the haploid and diploid daughter cells.

The daughter cells produced in mitosis and meiosis differ in the number of chromosomes present.

Therefore, the given option is false.

Explanation of option “(D)”

Homologous chromosome synapse is the specific structure that is formed during the meiosis process. Synapse is formed by overlapping of chromosomes with each other. It is not formed in the mitosis process.

Homologous chromosome synapse is seen only in meiosis.

Therefore, the given option is false.
