Attempt This Question
Not attemptedCorrect Answer: (b) the full range of mRNA molecules expressed by an organism
The ‘transcriptome’ is defined as the full complement of messenger-RNA (mRNA) molecules expressed by an organism (or by a specific cell/tissue at a given time). It is not an enzyme set, a mutation mechanism or merely a description of gene-expression processes. ([nature.com](https://www.nature.com/scitable/definition/transcriptome-296/))
