DNA Composition and Replication

Front

What are the four bases of DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G)

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is a template strand in DNA replication?

Back

The original strand of DNA that serves as a guide for the synthesis of a new complementary strand.

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transcription of genetic information.

Front

What happens during the initiation phase of DNA replication?

Back

The DNA double helix unwinds and separates at specific locations called origins of replication.

Front

What is the difference between leading and lagging strands 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 function of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of the DNA double helix.

Front

What is the role of ligase in DNA replication?

Back

DNA ligase joins Okazaki fragments on the lagging strand to create a continuous DNA strand.
