Answer:

The answer is DNA replication process.

Explanation:

Before reproduction takes place it is necessary to replicate all the DNA of the cell so that the new cell carries its own copy of the genetic material. The structure of the DNA molecule makes replication easier. Each side of the double helix is replicated in opposite directions. The DNA replication process is the mechanism that allows DNA to duplicate. In this way of a single DNA molecule, two or more "replicas" of the first and last are obtained.

Inessa05 [86]

Answer:

The correct answer will be-

1. Mitosis

2. Meiosis

3. Mitosis

4. Meiosis

5. Meiosis

6. Meiosis

Explanation:

A cell can divide by one of the two ways of cell division which are: Mitosis and Meiosis.

During mitosis, a cell undergoes four stages of distribution of nuclear material which are prophase, metaphase, anaphase, and telophase and easily characterised.

The mitosis division produces cells with the same genetic material called clones and is involved in the division of the somatic cells. This helps in the growth and repair of the damaged tissue.

Meiosis type of cell division divides and form the four haploid cells from parental cells. The process produces haploid cells in two stages: Meiosis I and Meiosis II. The tetrad formation takes place during the prophase I of the meiosis I.
