DNA Replication JC

Front

What is DNA replication?

Back

The process by which a DNA molecule makes a copy of itself, resulting in two identical DNA molecules.

Front

What is an addition mutation?

Back

A type of mutation where one or more nucleotide bases are added to the DNA sequence, potentially altering the resulting protein.

Front

What is a deletion mutation?

Back

A type of mutation where one or more nucleotide bases are removed from the DNA sequence, which can lead to a shift in the reading frame.

Front

What are the bonds that hold the two strands of DNA together?

Back

Weak hydrogen bonds between the nitrogenous bases of the two strands.

Front

What is the structure of DNA described as?

Back

A double helix, resembling a twisted ladder.

Front

What is the role of DNA polymerase in replication?

Back

An enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the 5' to 3' direction in DNA replication?

Back

DNA strands are synthesized in the 5' to 3' direction, meaning nucleotides are added to the 3' end of the growing strand.

Front

What is the function of helicase in DNA replication?

Back

An enzyme that unwinds the DNA double helix, separating the two strands to allow replication.

Front

What is the leading strand in DNA replication?

Back

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

Front

What is the lagging strand in DNA replication?

Back

The strand that is synthesized discontinuously in short segments, known as Okazaki fragments, in the opposite direction of the replication fork.
