Which process must occur first before any cell division can take place

Answers

Fertilization bc that's what i got and it was right

Final answer:

DNA replication is the process that must occur first before any cell division can take place.

Explanation:

In order for cell division to take place, a process called DNA replication must occur first. DNA replication is the process by which the genetic material (DNA) is copied to produce two identical copies. This ensures that each new cell will have an exact copy of the genetic material.

DNA replication occurs during the interphase stage of the cell cycle, specifically during the S phase. The S phase is the time when the cell prepares for division by duplicating its DNA.

During DNA replication, the double-stranded DNA molecule unwinds and separates into two separate strands. Each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules.
