Front

What is a nucleotide composed of?

Back

A nucleotide is composed of a phosphate group, a sugar (deoxyribose in DNA), and a nitrogenous base.

Front

What holds the two strands of DNA together?

Back

The two strands of DNA are held together by hydrogen bonds between complementary nitrogenous bases.

Front

What is the backbone of DNA made of?

Back

The backbone of DNA is made of alternating sugar and phosphate groups.

Front

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is usually single-stranded.
