Genes that are involved in turning on or off the transcription of a set of structural genes are called:
Correct answer: D. Operator genes
- A. Redundant genes
- B. Regulatory genes
- C. Polymorphic genes
- D. Operator genes
Explanation
Operator genes are a region of DNA sequence capable of interacting with a specific repressor molecule, and in doing so, they affect the activity of other genes downstream from them.The other options are incorrect because :Regulator genes code for proteins that bind to DNA and regulate the expression of other genes.Redundant genes are genes that code for the same or similar proteins.Polymorphic genes are genes that have different variants in a population.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
