What does the field of proteomics study?

Hint: Every word consists of a mixture of two words which helps to identify what it is used for like the word proteomic consists of part of the word protein which means it is related with the protein like the word proteome which describes the set of the protein encoded by the genome.

Complete answer:
The field of proteomics helps in the study of the structure and function of proteins. It is commonly used for the study and treatment of proteomics by cancer proteomics in which different types of biomarkers of protein are used to study and detection of cancerous cells and with the help of this, the drug is prepared for the treatment of cancerous cells.

Additional Information:
Proteomics is the technology in current systems that helps in the deep molecular study of diseased or normal genes. The study through proteomics also helps in the discovery of drugs by the study of diseased or normal tissue with the help of transcription, expressing profiling and pharmacogenomics. The set of genes in all organisms remain the same but the protein produced depends upon the set of codons produced by the nucleus.
The sequence of the protein that forms during the translation process helps in determining cellular function. The proteomics depends upon the bioinformatics process to read the protein data.

Note:
The word proteomics was first used in 1997 and the word proteome was made by combining two words protein and genome in 1994 by Mark Wilkins. Before the study through proteomics, it is suggested to first analyse the mRNA because all mRNA is not translated into protein.
