Question

What is proteomics?
A. The linkage of each gene to a particular protein
B. The totality of the functional possibilities of a single protein
C. The study of the full protein set encoded by a genome
D. The study of how amino acids are ordered in a protein

Answer 1

Hint: The wide-scale study of proteomes is called proteomics. Proteomes are the whole set of proteins encoded by a genome.

Complete answer: Large-scale study of proteomes is known as proteomics. It deals with a complete set of proteins produced in an organism, system, or biological context. The entire complement of proteins produced or encoded by a genome is referred to as a proteome. It may also include the modifications made to a specific set of proteins in an individual.

Additional information: Proteomics depends on three basic technological cornerstones that consist of a method to fractionate complex protein or peptide mixtures, MS to acquire the data necessary to find individual proteins, and bioinformatics to analyze and assemble the MS data.

So, the correct option is C. The study of the full protein set encoded by a genome.

Note: More appropriately, the study of a specific proteome or the entire set of proteins in proteomics. It also includes information such as protein abundances, modifications, variations, rates of protein production, degradation, movement of proteins between subcellular compartments, the involvement of proteins in metabolic pathways, the interaction between proteins, etc.
