Solution
Mitosis:
In cell biology, the cell cycle phase known as mitosis is when replicated chromosomes are divided into two new nuclei.
DNA synthesis is a vital event that takes place before mitosis.
Event occurring before mitosis:
DNA replication occurs in the S-phase of the interphase.
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:
Meiosis is a specialized form of cell division in which number of chromosomes is reduced to half.
Meiosis is divided into two parts: meiosis I and meiosis II.
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:
DNA replication should not occur after meiosis I.
The goal of meiosis is to create a haploid gamete after it has begun. Therefore, there is no need for additional replication.
There is no interphase between meiosis I and meiosis II.
