KEY CONCEPT DNA replication copies the genetic information of a cell.

________________ copies the genetic information. A single strand of DNA serves as a template for a new strand. The rules of base pairing direct replication. DNA is replicated during the __ (__________) stage of the cell cycle. Each body cell gets a complete set of identical DNA.

Proteins carry out the process of replication. DNA serves only as a template. __________ and other __________ do the actual work of replication. Enzymes __________ the double helix. Free-floating nucleotides form ___________ bonds with the template strand. nucleotide The DNA molecule unzips in both directions.

______ _____________ enzymes bond the nucleotides together to form the double helix. Polymerase enzymes form ___________ bonds between nucleotides in the new strand. DNA polymerase new strand nucleotide

DNA replication is ___________________. ______ new molecules of DNA are formed, each with an __________ strand and a _________ formed strand. DNA replication is ___________________. original strand new strand Two molecules of DNA

Replication is fast and accurate. DNA replication starts at many points in ___________ chromosomes. There are many origins of replication in eukaryotic chromosomes. DNA _____________ can find and correct errors.
