The genes are transcribed to pre-messenger RNA, further processed to messenger RNA (transcripts), and finally translated into protein. The transcriptome constitutes the complete set of different transcripts that is synthesized in the lifetime of a cell or a tissue. The proteome refers to the complete set of proteins that is expressed, and modified following expression in the lifetime of a cell or a given tissue. Transcriptomics refers to the study of the transcriptome, while proteomics refers to the study of the proteome using large-scale technologies for transcript or protein analyses. The two disciplines each provide unique information and supplement each other.
