Question

What is transcriptional control of gene expression?

Answer 1

Gene Expression:

1. Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
2. In molecular biology and genetics, transcriptional regulation refers to the mechanism through which a cell controls the transcription (or orchestration) of DNA into RNA.
3. At the transcriptional level, gene expression can be controlled.
4. The amount of mRNA generated by a specific gene in the DNA is regulated.
5. The transcriptionally controlled machinery in the lac operon was first shown by Jacob and Monad.
