D) the levels of mRNAs present in a particular cell type
E) the movement of transposable elements within the genome

Question

Quizplus · Accepted Answer

Proteomics can reveal the set of proteins present within a cell or tissue type, which genomics cannot do as it only focuses on the sequence and organization of genes within the genome. While alternative splicing patterns can also be analyzed through proteomics, this is not a definitive difference from genomics as some genomic techniques can also detect alternative splicing events. Proteomics can also provide information on post-translational modifications of proteins, protein-protein interactions, and protein localization, all of which are not accessible through genomics.
