DNA Replication

Front

What is DNA replication?

Back

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

Front

True or False: The new DNA strand formed after DNA replication is an exact copy of its parent strand.

Back

True

Front

What is the shape of DNA?

Back

Double helix.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of sugar, phosphate, and nitrogenous bases.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What type of bond holds the two strands of DNA together?

Back

Weak hydrogen bonds between the nitrogenous bases.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transmission of genetic information.

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

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