AP Bio Insta-Review Topic 6.2*: Replication

Front

Which direction is DNA read by DNA Polymerase?

Back

3’ to 5’

Front

Which direction is DNA synthesized by DNA Polymerase?

Back

5’ to 3’

Front

How is the lagging strand synthesized?

Back

Discontinuously

Front

What is the orientation of double stranded DNA?

Back

Antiparallel

Front

True or False: Chargaff's experiments showed that the amount of A, T, G and C is the same from species to species.

Back

False

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double helix, separating the two strands of DNA.

Front

What is the significance of the 5’ and 3’ ends of a DNA strand?

Back

The 5’ end has a phosphate group, while the 3’ end has a hydroxyl group, determining the direction of synthesis.

Front

What is the leading strand in DNA replication?

Back

The leading strand is synthesized continuously in the same direction as the replication fork.
