8.3 DNA Replication Topic: DNA replication Objective: DNA replication is when DNA is copied. nucleotide The DNA molecule unzips in both directions.

8.3 DNA Replication Replication copies the genetic information. A single strand of DNA serves as a template for a new strand. General Description: DNA is replicated during the S (synthesis) stage during Interphase of the cell cycle..IS COPIED

8.3 DNA Replication LETS IDENTIFY THE STRUCTURES ON THE RIGHT FIRST 1.PHOSPHATE AND SUGAR BACKBONE 2.BASES 3.FREE FLOATING BASES WITH ENZYME 4.NEW STRAND OF DNA

8.3 DNA Replication Proteins carry out the process of replication. Process: 1. Enzyme is called HELICASE unzips the double helix 2. Free-floating bases pair with the exposed bases that have been unzipped nucleotide The DNA molecule unzips in both directions. nucleotide The DNA molecule unzips in both directions.

8.3 DNA Replication 3. Another enzyme, DNA polymerase, bond the nucleotides together to form the double helix DNA polymerase new strand nucleotide

8.3 DNA Replication original strand new strand Two molecules of DNA 4. END RESULT: Two new molecules of DNA are formed Original is blue, new is orange.
