What must happen before meiosis can begin

Before meiosis can begin, chromosomes must replicate.

Before meiosis can take place in a cell, such a cell must go through the interphase stage of the cell cycle.

During the interphase, the cell grows in size and volume (G1 phase) and chromosome replications occur (S phase). Thereafter, the cell synthesizes protein (G2) before being ready to undergo meiotic cell division.

The correct answer is option C.

Explanation:

Before meiosis, DNA that is stacked into chromosomes must replicate. Before replication, the sex cell has two copies of each chromosome, one from mother, and one from father.

DNA replication takes place in the same manner as it does during mitosis. After the chromosome replication, the homologs are double in number, and each chromosome now has a homologous pair of chromosomes.

Thus, the correct answer is option C.
