3. What is name for the process by which new copies of DNA are made?

DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule.

Explanation:

DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).

Purpose of DNA makes an exact copy of itself prior to cell division; ensures that each new cell gets a complete copy of the DNA. First Helicase attaches to DNA and brakes Hydrogen bonds between bases- DNA chain unwinds and unzips. Special proteins keep it unzipping . Second RNA primase adds an RNA primer.
