Which statement best describes genetic material? A. A single gene contains hundreds of proteins that have the code for
making more genes.
B. Chromosomes are sections of DNA that have the codes for amino
acids
C. Genes are made up of chromosomes that are packaged tightly in
DNA
D. A single gene has the code for the series of amino acids that
makes a protein.

D. A single gene has the code for the series of amino acids that

makes a protein.

Explanation:

Genes are functional units of heredity and they are made of DNA that is packaged in components called chromosomes.

Each gene carry a genetic code which codes for the series of amino acid creating a specific protein.  In general, the genetic code specifies 20 standard amino acids that form proteins.

Hence, the best statement describes genetic material is "D" and other given options are incorrect.
