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

  1. A.A range of enzymes used in genome editing
  2. B.The full range of mRNA molecules expressed by an organism
  3. C.The description of the mechanism of gene expression
  4. D.A mechanism of genetic mutations taking place in cells
▶ Answer & Explanation

Correct answer: B. The full range of mRNA molecules expressed by an organism

The transcriptome encompasses all the messenger RNA (mRNA) transcripts present in a cell or population of cells at a specific time. It represents the genes that are actively being expressed. mRNA molecules are transcribed from DNA and carry the genetic code for protein synthesis, making the transcriptome a dynamic snapshot of gene activity.
