Front

What is the basic unit of DNA?

Back

Nucleotide

Front

What are the three components of a nucleotide?

Back

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

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

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

Back

The double helix structure allows for the compact storage of genetic information and provides stability.

Front

What is the function of the hydrogen bonds in DNA?

Back

Hydrogen bonds between complementary bases hold the two strands of DNA together.
