Proteomics is defined as the

a) linkage of each gene to a particular proteinb) study of the full protein set encoded by a genomec) totality of the functional possibilities of a single proteind) study of how amino acids are ordered in a protein

C) totality of the functional possibilities of a single protein

Explanation:

Proteomics is the study of proteins and their different aspects. It helps in describing the proteins, their structure and function. The wide field of proteomics helps in detection of the expression patterns of the protein at a given time in response to a specific stimulus.

The functional area of protein exist at different levels like cells, tissues and the entire organism. The proteins are the building blocks of life thus they are important for cellular metabolism and physiological functions in the body of the host.
