Answer:
C, Nucleic acids
Step-by-step explanation:
The Deoxy ribosenucleic acid (DNA) is a molecule that contains in it, instructions required for an organism to function. A segment of this DNA ( a sequence of nitrogenous bases), which is the basic hereditary material, that codes for a specific protein is called a GENE. The genes are transcripted into messenger RNA (mRNA) which are later translated into a sequence of three nucleotides that codes for an amino acid, called CODONS. These codons forms an amino acid sequence (proteins) which are responsible for the phenotypic characteristics of an individual, called traits.
This process of gene expression commenced with DNA, which is a Nucleic acid, it can therefore be said that the Nucleic acid codes for the traits of an organism.
