DNA Structure and Replication

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life.

Front

What are the building blocks of DNA?

Back

Nucleotides are the building blocks of DNA.

Front

What are the three components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose), 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 shape of the DNA molecule?

Back

DNA has a double helix shape.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is the enzyme responsible for adding free nucleotides to the growing DNA strand during replication.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the function of DNA?

Back

DNA serves as the blueprint for the traits of all living things.

Front

What is the significance of complementary base pairing?

Back

Complementary base pairing ensures accurate DNA replication and the preservation of genetic information.
