Question

Proteomics refers to the study of

• A. Set of proteins in a specific region of the cell
• B. Biomolecules
• C. Set of proteins
• D. The entire set of expressed proteins in the cell

Hint:

• Genome Entire set of genes of an organism. Genomics Study of genomes.
• Transcriptome Entire set of RNA transcripts in a cell/organism. Transcriptomics Study of transcriptomes.
• Proteome Entire set of proteins expressed by a genome, cell, tissue, or organism at a certain time. Proteomics Study of proteomes.
• Proteomics is more complex than genomics because protein expression is dynamic and proteins undergo many post-translational modifications.

Answer 1

The Correct Option is D

Proteomics is the large-scale study of proteins, particularly their structures and functions. Proteins are vital parts of living organisms, as they are the main components of the physiological metabolic pathways of cells. The term proteomics refers to:

The study of the entire set of expressed proteins in the cell. This encompasses all the proteins encoded by an organism's genome, including those in various conditions, situations, and functions within the cell.

Proteomics aims to:

• Understand interactions, modifications, and functions of proteins.
• Define the structure, activity, and function of proteins in various states.
• Identify potential biomarkers for diseases.

The correct answer to the study of proteomics is the entire set of expressed proteins in the cell, highlighting its comprehensive scope within the field of biotechnology.
