Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.

Front

What are the four nitrogenous bases in DNA?

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

Front

What is the structure of DNA?

Back

DNA is a double helix formed by two strands of nucleotides.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix.

Front

What is the function of DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.
