Bioinformatics and Transcriptome
Question
In the context of the developments in Bioinformatics, the term 'transcriptome', sometimes seen in the news, refers to
Options
a range of enzymes used in genome editing
the full range of mRNA molecules expressed by an organism
the description of the mechanism of gene expression
a mechanism of genetic mutations taking place in cells
Explanation
Transcriptome refers to the complete set of all mRNA molecules transcribed from the genome of an organism. It represents the functional expression of genes at any given time in a cell or tissue. Option (a) describes enzymes used in genome editing, which is not transcriptome. Option (c) describes the process, not the molecule itself. Option (d) refers to genetic mutations, which is distinct from transcriptome. Transcriptome is the collection of all mRNA transcripts produced from a genome, making it the most accurate definition of gene expression products at the molecular level.
Answer: (b).
