Answer: i think the answer is b. To activate gene expression; the level of gene expression increases because repressors are not able to bind to the enhancer without the control element.
Explanation:
If deletion of a control element causes a decrease in gene expression, the normal role of that control element is to: B. To activate gene expression; the level of gene expression increases because repressors are not able to bind to the enhancer without the control element.
Genetics can be defined as the scientific study of hereditary and its components (genes) within the body of an organism such as an animal, human, and plant.
Genome editing refer to a high-tech process through which scientists delete (remove), replace or insert a deoxyribonucleic acid (DNA) sequence into the cells of a living organism, so as to improve on both its physical and chemical conditions or cure (correct) a genetic disorder in some instances.
Gene expression simply means the transcription of a gene into a messenger ribonucleic acid (mRNA), as well as its subsequent translation into protein.
Hence, gene expression is typically controlled on two (2) main levels and these are:
When the deletion (removal) of a control element causes a decrease in gene expression, its normal role would be to activate (increase) gene expression because the repressors won't be able to bind to the enhancer without this control element.
On the other hand, when the deletion (removal) of a control element causes an increase in gene expression, its normal role would be to repress (decrease) gene expression because the activators won't be able to bind to the enhancer without this control element.
