Answer:

1. Mitosis

2. Bases

3. Hydrogen

Explanation:

1. DNA replication occurs prior to meiosis and mitosis.

mitosis - cytokinesis - transcription

In cell division, DNA synthesis and replication is carried out during the S phase, in the interphase, a stage that occurs before mitosis and meiosis.

2. Adenine with Thymine and Cytosine with Guanine are known as the nitrogen bases in DNA.

bonds - bases - amino acids

Nucleic acids (DNA and RNA) are composed of nucleotides that contain nitrogenous bases:

DNA: adenine (A), guanine (G), thymine (T), and cytosine (C).

RNA: adenine (A), uracil (U), guanine (G), and cytosine (C).

3. Hydrogen bonds form and hold the DNA together.

hydrogen - peptide - polar

The complementary nitrogen bases are held together by hydrogen bonds:

A=T (adenine pairs with thymine)

C=G (cytosine pairs with guanine)
