In the context of the developments in Bioinformatics, the term 'transcriptome', sometimes seen in the news, refers to

The transcriptome refers to the complete set of RNA transcripts, specifically the full range of mRNA molecules expressed by an organism's genome under specific conditions. This core concept of bioinformatics focuses on the functional output of the genome, distinguishing the dynamic collection of expressed genes from the static DNA sequence (genome). Option (c) is the most tempting distractor but is incorrect because it refers to the *process* or mechanism of gene expression rather than the resulting *set* of molecules produced.
