What primary method does the cell employ to ensure gene expression only occurs when necessary?

Limited amounts of specific DNA

Phosphorylation cascade with multiple steps

Receptors that only fit specific hormones

Unique transcription factors made of carbohydrates

Respuesta :

Answer:

Unique transcription factors made of carbohydrates

Explanation:

Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.

Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.

Answer: receptors that only fit specific hormones
