Genes and Proteins – Check Test

1. The function of DNA is to

A act as an enzyme.

B release energy in cells.

C carry genetic instructions.

D form cell structure.

2. An amino acid is a unit of the structure of

A protein.

B DNA.

C carbohydrate.

D chromosomes.

3. Proteins are chains of

A bases.

B amino acids.

C sugars.

D genes.

4. An explanation of the genetic code is that

A base sequences of DNA determine the amino acid

sequence in a protein.

B amino acid sequences on DNA determine the base

sequence in a protein.

C amino acid sequences in protein determine the

base sequence in DNA.

D base sequences in protein determine the amino

acid sequence in DNA.

Questions 5, 6, and 7 relate to the following information

about DNA.

DNA bases Amino acid coded for

5. Which piece of protein would be made if the

following DNA sequence was read?

6. Which piece of protein would be made if

the following DNA sequence was read?

7. Which DNA sequence would give the following

piece of protein?

8. The three-dimensional shape of a protein molecule

such as an enzyme is important because it

A allows the enzyme to be specific.

B prevents the enzyme being denatured.

C makes the enzyme a larger size.

D increases the rate of the enzyme reaction.
