1. Gene regulation is the ability of an organism to control which genes are transcribed.

Gene regulation is the ability of an organism to control which genes are transcribed is a true statement.

Explanation:

Gene regulation is a process which regulate (by inducing or repressing) a gene expression.  

It can make structural or chemical alterations to the gene material. It regulates transcription by allowing proteins to bind only to specific elements on the DNA and modulates translation.  

Gene regulation simply turns genes “on or off”. The regulation action is done by activator proteins which induces or turns on a gene expression; while gene regulators repress or turns off the gene expression.

When a gene is turned on, it is ordered to code only for the specific protein. Only the respective required genes are turned on to specifically code for the specific proteins.

Thus the proteins can be coded into various types according to the function to be performed. The function and structure of a protein in a brain cell differs from that of a skin cell due to gene regulation .
