DNA 1 - Period 2

Front

What are the building blocks for DNA?

Back

Nucleotides are the building blocks of DNA.

Front

What determines the code, or information, of a DNA molecule?

Back

The order (sequence) of the nitrogen bases determines the code of a DNA molecule.

Front

What are the three components of a nucleotide?

Back

A nucleotide consists of sugar, phosphate, and a nitrogen base.

Front

Which organelle is DNA usually found in?

Back

DNA is usually found in the nucleus.

Front

Which of the following best describes a DNA molecule?

Back

A DNA molecule is best described as a double helix.

Front

What is the function of DNA?

Back

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

Front

What are nitrogen bases?

Back

Nitrogen bases are the components of nucleotides that pair together to form the rungs of the DNA ladder.

Front

Name the four nitrogen bases found in DNA.

Back

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

Front

What is the base pairing rule in DNA?

Back

The base pairing rule states that adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the role of the sugar in a nucleotide?

Back

The sugar in a nucleotide provides the backbone structure for the DNA molecule.
