1. Replication

2. The Central Points of Protein Synthesis Are: DNA duplicates itself in replication. DNA produces RNA in transcription. RNA produces proteins in translation.

4. Replication of DNA What happens in interphase of mitosis or meiosis? Process by which DNA makes a copy of itself Each new cell receives a copy of the DNA

5. Separation of strands DNA molecule separate at their base pairs Hydrogen bonds are broken DNA molecule unzips, exposing the nucleotides

6. Base pairing Free nucleotides base pair with exposed nucleotides If strand has thymine as a base what would the complementary base pair be If strand contains cytosine? Each strand builds its complement by base pairing

7. Bonding of bases Sugar and phosphate parts of nucleotides bond together to form backbone of the new strand Each original strand is now bonded to a new strand

8. Results of replication Process of replication produces two molecules of DNA Each new molecule has one strand from the original molecule and one strand that has been newly synthesized

9. Replication is called semi- conservative, one half of the original strand is always saved, or "conserved"
