Cell Cycle

This enzyme is responsible for creating telomeres added to the ends of DNA

• Topoisomerase

• Telomerase

• DNA Helicase

• DNA Primase

Why does DNA replicate?

• To create another copy for the new cell

• To create a duplicate copy in case the original gets damaged

• To create a new copy to replace the damaged original

DNA replication results in two DNA molecules,

• each one with two original strands

• each one with two new strands

• each one with one new strand and one original strand

• one with two new strands and the other with two original strands

DNA replication takes place at _________ phase of the cell
