Final answer:
Proteomics is the study of how proteins interact to form cell and tissue types, focusing on the entire set of proteins within an organism.
Step-by-step explanation:
The process that involves an examination of how the proteins encoded by genes interact to produce cell and tissue types is known as Proteomics. This field of study is an extension of genomics, focusing on the entire complement of proteins in an organism, referred to as the proteome. Proteomics is essential because, while all cells of a multicellular organism possess the same genes, they often produce different sets of proteins based on gene expression and environmental conditions, making the proteome dynamic and variable. This complexity requires the use of technologies such as protein microarrays and immunochemical techniques to analyze protein-protein interactions and modifications like phosphorylation, glycosylation, and ubiquitination.
