The basis of using proteomics to describe tissues is that
A) different cell types produce different sets of tRNAs.
B) different cell types produce different sets of mRNAs.
C) all cells produce the same amounts of the same proteins.
D) the genetic code is universal.

Question

Quizplus · Accepted Answer

Proteomics is the study of all proteins expressed in a given cell or tissue at a particular time. The basis of using proteomics to describe tissues is that different cell types produce different sets of mRNAs, which in turn lead to the production of different sets of proteins. Therefore, by analyzing the protein content of a tissue, researchers can identify the cell types present in that tissue based on the specific proteins being produced. Options A, C, and D are all incorrect because they do not adequately describe the basis of using proteomics to describe tissues.
