What is a section of DNA that contains the genetic code for a single protein called?

Back

A gene is a section of DNA that contains the genetic code for a single protein.

Front

What is the sugar component of a nucleotide in DNA?

Back

The sugar component of a nucleotide in DNA is deoxyribose.

Front

What is the basic building block of DNA?

Back

A nucleotide is the basic building block of DNA.

Front

What forms the rungs or steps of the DNA molecule?

Back

The rungs or steps of the DNA molecule are formed by nitrogenous bases.

Front

Which two molecules form the sides (backbone) of the DNA molecule?

Back

The sides (backbone) of the DNA molecule are formed by deoxyribose (sugar) and phosphate.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the process by which DNA is copied before cell division?

Back

The process by which DNA is copied before cell division is called DNA replication.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication of DNA and the preservation of genetic information.

Front

What is the structure of DNA described as?

Back

The structure of DNA is described as a double helix.
