NY Regents DNA replication

Front

What are the complementary base pairs in DNA?

Back

A-T and G-C are the complementary base pairs in DNA.

Front

What is the role of DNA Helicase in DNA replication?

Back

DNA Helicase unzips the DNA strands to prepare for replication.

Front

What is the function of DNA Polymerase?

Back

DNA Polymerase synthesizes new DNA strands by adding nucleotides to the growing chain.

Front

What are the three components of a DNA nucleotide?

Back

A DNA nucleotide is made up of a nitrogenous base, a sugar (deoxyribose), and a phosphate group.

Front

What is the result of DNA replication?

Back

The result of DNA replication is two identical double-stranded DNA molecules.

Front

What is the difference between the leading strand and the lagging strand during DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.

Front

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

Back

The 5' end has a phosphate group, and the 3' end has a hydroxyl group, which determines the direction of DNA synthesis.

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein function.

Front

What is the role of free nucleotides in DNA replication?

Back

Free nucleotides pair with the exposed bases on the unwound DNA strands to form new strands.

Front

What is the function of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA Polymerase to begin synthesis.
