The function of the nucleic acids contained in the body cells of an organism is
a
directing the synthesis of proteins necessary for proper cell function.

b
producing the inorganic molecules needed for normal cell growth.

c
disrupting meiosis and the synthesis of amino acids into a sequence.

d
forming a variety of gametes that will pass on hereditary information.

directing the synthesis of proteins necessary for proper cell function.

Explanation:

The nucleic acids include DNA and RNA. Instructions on DNA are transcribed into messenger RNA. Ribosomes are able to read the genetic information inscribed on a strand of messenger RNA and use this information to string amino acids together into a protein thus directing the synthesis of proteins necessary for proper cell function.
