Question

Which event occurs before mitosis and should never occur after meiosis I?

Answer 1

Mitosis:

1. In cell biology, the cell cycle phase known as mitosis is when replicated chromosomes are divided into two new nuclei.
2. DNA synthesis is a vital event that takes place before mitosis.

Event occurring before mitosis:

1. DNA replication occurs in the S-phase of the interphase.
2. Before dividing, cells must copy their DNA. This promotes the successful inheritance of genetic features by giving each daughter cell a copy of the genome.

Meiosis I:

1. Meiosis is a specialized form of cell division in which number of chromosomes is reduced to half.
2. Meiosis is divided into two parts: meiosis I and meiosis II.
3. The homologous pair of chromosomes are separated during meiosis 1, which also turns the diploid cell into a haploid.

Event that should never occur after meiosis I:

1. DNA replication should not occur after meiosis I.
2. The goal of meiosis is to create a haploid gamete after it has begun. Therefore, there is no need for additional replication.
3. There is no interphase between meiosis I and meiosis II.
