NGSS.HS-LS3-1

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

Which enzyme is responsible for adding bases?

• Topoisomerase

• DNA Polymerase

• Ligase

• Primase

Which DNA enzyme seals small gaps to finish DNA replication?

• Helicase

• DNA polymerase

• Primase

• Ligase

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

• Each new cell must have an exact copy of 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

What is the end result of replication?

• Two new identical strands of DNA
• One parent strand and one daughter strand of DNA
• Two new and different strands of DNA
• One new strand of DNA

What did Erwin Chargaff conclude from his experiments?

• Nitrogen bases are held together by peptide bonds
• A and T, C and G always occur in equal amounts
• Proteins are the carriers of genetic information
• C and G rarely occur in eukaryotic organisms

What was Watson and Crick's main scientific accomplishment?

• Building the first accurate model of DNA
• Isolating strains of pneumonia causing bacteria
• Determining base pairing rules
• Discovering the process of genetic transformation
