Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What is a nucleotide?

Back

A nucleotide is a monomer of nucleic acids made of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base.

Front

What sugar is found in DNA?

Back

The sugar found in DNA is deoxyribose.

Front

Which base does adenine bond with in DNA?

Back

Adenine bonds with thymine.

Front

What are the three components of a nucleotide?

Back

The three components of a nucleotide are sugar, phosphate, and nitrogen base.

Front

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

Back

The phosphate group links nucleotides together to form the backbone of DNA.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

Front

How do the nitrogenous bases pair in DNA?

Back

Adenine pairs with thymine, and cytosine pairs with guanine.
