Question

What does it mean when we say a gene is "turned off"? What does it mean when we say a gene is "turned off"? The gene is now activated. The gene cannot be transcribed and translated into a protein. The gene has a mutation. The gene is no longer working properly.

Answer 1

Answer:

The gene cannot be transcribed and translated into a protein.

Explanation:

Turning off a gene means the gene cannot be transcribed and translated into a protein.

Turning off of genes is a form of gene regulation, a process that controls which genes are expressed or not expressed in a cell.

The expression of genes requires that they are first transcribed from DNA to mRNA in the nucleus and then moved to cytoplasm where they are translated into proteins by the ribosome.

Hence, a gene that will not be expressed has to be stopped from being transcribed amd translated by being turned off by the gene regulation process of the cell.

Answer 2

Answer:

A GENE IS SAID TO BE TURN UP WHEN THEY GENE CANNOT BE TRANSCRIBED AND TRANSLATED INTO A PROTEIN.

Explanation:

Genes can be turned on and off bu cells which is the process of gene regulation. Gene regulation involves the mechanisms used by cells to induce or repress the expression of a gene which is an important part of normal development. Gene regulation involves structural changes made to the gene to ensure transcription occur or prevent transcription, the genes can be bound to a specific DNA receptor and the mechanism that modifies translation of mRNA. Gene regulation helps the cell determine which gene to be transcribed and the number of protein molecules to be made at any given time. Gene regulation occurs at any point of gene expression but its most common during transcription of DNA to an mRNA molecule. Signals from the environment activates transcription factors which determines the process of transcription by binding to the regulatory regions of the genes.
