1. DNA Replication

2. DNA replication – the process of making a copy of DNA; occurs during synthesis (S) phase of the cell cycle, prior to cell division
DNA helicase – an enzyme that opens the double helix by breaking the hydrogen bonds
DNA polymerase – an enzyme that moves along each side of the DNA strand adding the complimentary nucleotide; the DNA polymerase can backtrack to correct any errors or mutations

4. Multiple Replication Forks:
What effect do multiple replication forks have on the speed of replication in eukaryotic cells?
It speeds up the process.

5. DNA replication is referred to as semi- conservative replication
DNA replication is referred to as semi- conservative replication. Why is that? It is called semi- conservative because each new molecule is composed of one conserved strand from the original molecule and one new strand that was made.

6. The different strands in the helix run in opposite directions and are referred to as anti-parallel strands.
