DNA Replication
What is DNA Replication?
- Replication is the creation of a new strand of DNA. It copys one "backbone" of an old DNA, then attaches to a new one.
Where does DNA Replication happen?
- DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.
Why is DNA replication important?
- DNA replication assures that any daughter cells produced will have a complete copy of the DNA necessary for the cell to survive.
When does DNA replication happen?
- When a initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds, then this pullis apart the two strands.
Explain the process of DNA replication
- Helicase unwinds our double helix into two strands.
- Polymerase adds nucleotides to an existing strand.
- Ligase brings together the Okazaki fragments.
- Topoisomerase cuts and rejoins the helix.
-RNA primase catalyzes the synthesis of RNA primers.
