DNA Structure and Function practice

Front

What is the primary function of DNA in a cell?

Back

To store and transmit genetic information.

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine.

Front

What is the structure of DNA commonly described as?

Back

A double helix.

Front

What type of bond holds the nitrogenous bases together in the DNA molecule?

Back

Hydrogen bonds.

Front

What is a nucleotide composed of?

Back

A phosphate group, a sugar, and a nitrogenous base.

Front

Where in the cell is DNA primarily located?

Back

In the nucleus.

Front

What is the role of the phosphate group in a nucleotide?

Back

It forms the backbone of the DNA strand.

Front

How do adenine and thymine pair in DNA?

Back

They form two hydrogen bonds between them.

Front

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

Back

It ensures accurate replication and transcription of genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.
