Questions: Mitosis and meiosis are similar because both processes involve the replication of DNA before division.

The answer is the fourth one: Involve the replication of DNA before division.

Explanation for each option:

1. Produce diploid gametes from haploid cells: This is incorrect. Mitosis produces diploid daughter cells from diploid parent cells, while meiosis produces haploid gametes from diploid cells.

2. Produce daughter cells that are diploid: This is incorrect. Mitosis produces diploid daughter cells, but meiosis produces haploid daughter cells.

3. Make 4 cells: This is incorrect. Mitosis results in 2 daughter cells, while meiosis results in 4 daughter cells.

4. Involve the replication of DNA before division: This is correct. Both mitosis and meiosis involve the replication of DNA during the S phase of the cell cycle before the cell division processes begin.

Summary: Both mitosis and meiosis involve the replication of DNA before the cell division process starts, ensuring that the genetic material is duplicated and can be properly distributed to the daughter cells.
