Answer:
Before a cell reproduces, it must replicate or duplicate its DNA. This ensures that each new cell receives a complete copy of the genetic information needed for its normal functioning. During cell replication, the DNA double helix unwinds and separates, and each strand serves as a template for the formation of a new complementary strand. Once the replication is complete, the cell can undergo mitosis or meiosis to produce two or more daughter cells with identical or diverse genetic information, respectively.
