Answer:
(3). both mitosis and meiosis.
Explanation:
DNA replication can be defined as a process, which involves synthesis of daughter DNA molecules by using parent DNA as template. Mitosis and meiosis are two types of cell division. Mitosis occurs in somatic cells, white meiosis occurs in germ cells.
DNA replication occurs before both mitosis and meiosis as both somatic and germ cells replicate their genetic material prior to nuclear division to divide it into newly formed daughter cells.
Thus, the correct answer is option (3).
