To understand DNA replication, we need to understand the “why.” Why does DNA need to replicate before cells divide?

DNA Replication has many key players (enzymes)! These are just a few of the major enzymes. Match the enzymes in DNA replication to their functions in DNA replication.
| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Primase | arrow_right_alt | Enzyme that unzips the the double-stranded DNA by breaking the hydrogen bonds holding the bases together |
Helicase | arrow_right_alt | Enzyme that builds a new DNA molecule by adding complementary strands of DNA to the original, unzipped DNA molecule |
Ligase | arrow_right_alt | Enzyme that synthesizes a primer so DNA polymerase knows where to begin working |
DNA Polymerase | arrow_right_alt | Enzyme that binds or "glues" fragments of DNA together |
