Replication

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication

• Translation

• Transcription

order of replication

• 3, 2, 1, 4

• 2, 1, 4, 3

• 2, 3, 1, 4

• 3, 4, 1, 2

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

What is the purpose of DNA replication?

• Cut the DNA 

• Make more cells

• Apoptosis

• Duplicate the DNA

Which enzyme seals okazaki fragments together on the lagging strand?

• Topoisomerase

• Helicase

• Polymerase

• Ligase

What do we call DNA replication since new DNA has 1 parent strand and 1 new strand?

• Conservative 

• Semiconservative 

• Dispersive

Which enzyme is responsible for adding nucleotides?

• Topoisomerase

• DNA Polymerase

• Ligase

• Primase

This enzyme is capable of breaking Hydrogen bonds found between the bases of DNA

• Topoisomerase

• DNA Helicase

• DNA Polymerase

• Exonuclease

This enzyme is used to remove short RNA bases

• Topoisomerase

• DNA Helicase

• Exonuclease

• Telomerase

Why is it crucial that living things are able to replicate their DNA?

• Each cell must have its own DNA

• Less copies of DNA are needed when a new cell is created

• A cell needs multiple copies of DNA

• Only muscle cells need DNA
