Presentation Transcript

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

  2. Replication copies the genetic information. • A single strand of DNA serves as a template for a new strand. • The rules of base pairing directreplication. • DNA is replicated during theS (synthesis) stage of thecell cycle. • Each body cell gets acomplete set ofidentical DNA.

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

  4. nucleotide new strand DNA polymerase • DNA polymerase enzymes bond the nucleotides together to form the double helix. • Polymerase enzymes form covalent bonds between nucleotides in the new strand.

  5. new strand original strand Two molecules of DNA • Two new molecules of DNA are formed, each with an original strand and a newly formed strand. • DNA replication is semiconservative.

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