Question

Which process MUST occur before mitosis and meiosis can occur?

Answer 1

What MUST occur before mitosis and meiosis can occur is B) DNA replication. DNA replication is a process of copying DNA into an identical copy. Before mitosis, the genetic material of the mother cell must duplicate so that each daughter cell have the same amount as the mother cell. On the other hand, meiosis is a reductive division. But meiosis II is similar to mitosis, so DNA replication is also necessary.

Answer 2

DNA replication is a process of copying DNA into an identical copy.

So the right answer is b) DNA replication
