What is gene regulation?
1 Answer
Gene regulation is how genes are turned on or off and is accomplished through regulatory proteins or chemical modification of genes.
Explanation:
Gene regulation is how genes are turned on or off: it determines the amount of protein or RNA that a gene produces and the rate at which this production occurs. Gene regulation is accomplished through regulatory proteins or chemical modification of genes. It allows an organism to respond to its environment when needed.
Gene regulation happens in transcription, translation, or after translation.
During transcription, mRNA is produced, which determines the sequence of amino acids in the protein product, the sequence of tRNA and the sequence of rRNA. In translation, the mRNA produced earlier is read and used as a template to create the amino acid sequence in proteins.
Gene regulation can affect the rate of transcription or translation, it can affect splicing, and so forth. The main way genes are regulated is through affecting the rate of transcription.
