(b) if loss of a control element causes a reduction in gene expression, what must be the normal role of that control element? provide a biological explanation for how the loss of such a control element could lead to a reduction in gene expression



Answer :

Control element 3's deletion lowers the gene's level of expression. Accordingly, the control element's function is to initiate the expression of genes. This is due to the role of control elements in controlling gene expression, such as the promoter or enhancer region.

What is gene expression?
Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and eventually have an impact on phenotypes.

Hence,  the control element's function is to initiate the expression of genes. This is due to the role of control elements in controlling gene expression, such as the promoter or enhancer region.
