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

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

• Topoisomerase

• DNA Helicase

• DNA Polymerase

• Exonuclease
