Gene function is annotated based on homology between the ORFs of a genome and proteins whose function has been proven experimentally. What ʺ-omicʺ approach could help us determine the function and structure of proteins encoded by uncharacterized ORFs?
A) metabolomics
B) metagenomics
C) transcriptomics
D) proteomics
