What is a proteome?
A
The number of genes found in a organism
B
The number of proteins produced by an organism
C
The number of amino acids found in an organism
D
The number of amino acids found in a polypeptide
Explanation: 

Detailed explanation-1: -A proteome is a set of proteins produced in an organism, system, or biological context. We may refer to, for instance, the proteome of a species (for example, Homo sapiens) or an organ (for example, the liver). The proteome is not constant; it differs from cell to cell and changes over time.

Detailed explanation-2: -(PROH-tee-ome) The complete set of proteins made by an organism. Proteins are made in different amounts and at different times, depending on how they work, when they are needed, and how they interact with other proteins inside cells.

Detailed explanation-3: -The number of different proteins comprising the human proteome is a core proteomics issue. Researchers propose numbers between 10, 000 [10] and several billion [6] different protein species.

Detailed explanation-4: -The word proteome was created by Marc Wilkins in 1995[1]. Proteomics is the study of the interactions, function, composition, and structures of proteins and their cellular activities[2]. Proteomics provides a better understanding of the structure and function of the organism than genomics.

Detailed explanation-5: -The importance of the proteome cannot be overstated as it is the proteins within the cell that provide structure, produce energy, as well as allow communication, movement, and reproduction. Basically, proteins provide structural and functional framework for cellular life.
