Of all the cis-acting elements associated with a gene, which is the most important? Why?

Expert Solution

Ans: Cis-acting elements associated with the genes are sequences of the DNA which are non transcribed regions. which regulate the expression of gene. some esamples are Promoters, Enhancers and Silencers. A promoter is a Cis acting regulatory element that reguglates the transcription of DNA sequence adjacent to it. It is a non transcribed region. promoter is the binding site for the RNA polymerase during the initiation or transcription. the rate of the expression of a gene is determined by the strenth of the promoter which in turn is dependent on the sequence of the promoter. Promoter is the most important Cis-acting element associated with gene because mutations in the promoter sequence, decrease or completely abolish the affinity for RNA polymerase binding and results no transcription occur(no gene expression).

The necessary components for gene expression are often described as either cis-acting elements (“acting from the same molecule”) or trans-acting factors (“acting from a different molecule”). Cis-acting elements are typically sequences that are required for expression. Trans-acting factors are typically proteins that recognize and bind cis-acting sequences to control or facilitate gene expression. For each of the cis-acting elements below, Promotor and Start Codon,list a trans-acting factor involved in its recognition and describe the factor’s normal function

Explain why it is ‘logical’ that cis-acting sequences that help enhance gene transcription rates are located upstream of the promotor, while the cis-acting sequences for negative effectors or repressors are typically located downstream, or even within, the promoter region of the gene.
