6. When does the DNA in a cell replicate? a. before cell division (mitosis or meiosis)
b. during cell division (mitosis or meiosis)
after cell division (mitosis or meiosis)
d. at random times throughout the cell's life cycle

the answer is A before cell division (mitosis or meiosis)

Explanation:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
