Answer:
C. genes
Explanation:
Genes are basic physical & functional unit of heredity. Genes are made up of DNA or we can say that they are segments of DNA which have instructions to synthesize bio molecules known as proteins and these protein molecules are further responsible for characteristics of an organism. Genes are located at a specific location in our chromosomes and the location is known as locus. Almost all the characteristics which an organism has depend upon the kind of information they have in their genes.
During developmental stages, how an organism will develop totally depends upon what kind of proteins are being synthesized at that time and as already explained, protein synthesis totally depends upon type of genes present in the organisms.
