DNA Structure

Front

What is the structure of DNA?

Back

DNA is a double helix formed by two strands of nucleotides twisted around each other, held together by base pairs.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What is a nucleotide composed of?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What is the monomer of DNA?

Back

The monomer of DNA is a nucleotide.

Front

Where is DNA located in a cell?

Back

DNA is primarily located in the nucleus of eukaryotic cells.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What is the role of the sugar in a nucleotide?

Back

The sugar (deoxyribose) forms the backbone of the DNA strand, linking the phosphate groups.

Front

What is complementary base pairing?

Back

Complementary base pairing refers to the specific pairing of nitrogenous bases: Adenine with Thymine, and Cytosine with Guanine.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the efficient storage of genetic information and the accurate replication of DNA.
