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

What are the building blocks of DNA?

Back

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

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

How do the nitrogenous bases pair in DNA?

Back

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

Front

What is the structure of DNA?

Back

A double helix formed by two strands of nucleotides twisted around each other.

Front

What does 'antiparallel' mean in the context of DNA strands?

Back

The two strands of DNA run in opposite directions; one runs 5' to 3' and the other runs 3' to 5'.

Front

What enzyme is responsible for unwinding the DNA double helix during replication?

Back

Helicase.

Front

What is the role of DNA polymerase in DNA replication?

Back

It adds nucleotides to the growing DNA strand and proofreads the new DNA.

Front

What is a replication fork?

Back

The Y-shaped region where the DNA is split into two strands for replication.

Front

What is the significance of complementary base pairing in DNA replication?

Back

It ensures that the new DNA strands are exact copies of the original strands.
