AP Biology DNA Structure

If a portion of DNA strand reads:

3' A A A T T T C 5'

The matching strand would read...

• 5' T T T A A A G 3'

• 3' T T T A A A G 5'

• 5' A A A T T T C 3'

• 3' U U U A A A G 5'

The strand of DNA that is replicated continuously from 5' to 3' is known as

• leading strand

• lagging strand

• parallel strand

• antiparallel strand

Which enzyme is responsible for adding the RNA primer to the template strand?

• Helicase

• DNA Polymerase

• Ligase

• Primase

Who is responsible for producing this image?

• Francis Crick and James Watson

• Erwin Chargaff

• Rosalind Franklin

• Alfred Hershey

What enzyme keeps DNA from overwinding ahead of replication forks?

• Primase

• Topoisomerase

• Single-Stand Binding Protein

• Helicase

When does DNA Replication occur?

• Just before the cell divides

• Just after the cell divides

• The M phase

• The S phase

Which macromolecule is primarily responsible for the storage of genetic information?

• Carbohydrates

• Lipids

• Proteins

• Nucleic acids
