When is the DNA replicated during meiosis?
Understand the Problem
The question is asking about the specific stage in meiosis when DNA replication occurs. This refers to the cellular process where the genetic material is duplicated so that each new cell can inherit a complete set of DNA.
Answer
Interphase, during the S phase.
The final answer is interphase, during the S phase.
Answer for screen readers
The final answer is interphase, during the S phase.
More Information
DNA replication occurs only once before the start of meiosis, in the S phase of interphase, ensuring that each chromosome consists of two sister chromatids.
Tips
A common mistake is to think DNA replicates during the actual stages of meiosis (prophase, metaphase, etc.), rather than before it in the S phase of interphase.
