Question

which process must take place before mitosis can occur properly?

active transport

aerobic respiration

dna replication

protein synthesis

Explanation:

Mitosis is a cell division process. Before mitosis, DNA replication must occur. DNA replication ensures that each daughter cell gets a complete set of genetic information. Protein synthesis is for making proteins, aerobic respiration is for energy production, and active transport is for moving substances across membranes. None of these are as fundamental as DNA replication for proper mitosis.

Answer:

DNA replication
