8.3 DNA ReplicationDNA replication copies the genetic information of a cell. • A single strand of DNA serves as a ______________________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. • Enzymes and other ___________________________________ do the actual work of replication.
How does DNA replication happen?1. Enzymes ___________________________ the double helix.2. Free-floating ________________________________ form hydrogen bonds with the template strand.
• 3. DNA polymerase enzymes bond the nucleotides together to form the double helix. DNA polymerases can find and correct __________________.
4. Two new molecules of DNA are formed, each with an original strand and a newly formed strand.DNA replication is semi-conservative, meaning one ____________________________ and one new strand.
DNA replication starts at many points in eukaryotic chromosomes.How does replication conserve genetic information?• Each _________________ or ________________ strand of DNA
serves as a template, allowing 2 identical strands of DNA to be made. This means the information “_________________” the same or is “___________________________”.
The DNA molecule unzips in both directions.
