1. in your own words, describe dna replication.

answer:

Explanation:

DNA replication is the process where a cell makes an identical copy of its DNA. It begins with the unwinding of the double - helix structure by helicase. Then, DNA polymerase adds complementary nucleotides to each of the separated strands. This results in two new DNA molecules, each with one original and one new strand (semi - conservative replication).

Answer:

DNA replication is the process of creating an identical copy of DNA. The double - helix unwinds (by helicase), and new complementary nucleotides are added (by DNA polymerase) to each strand. It follows a semi - conservative model, resulting in two DNA molecules each with one old and one new strand.
