Which of the following clusters of terms apply when addressing enhancers or silencers as elements associated with eukaryotic genetic regulation? A)cis- acting,variable orientation,variable position B)trans- and cis- acting,variable position C)cis- acting,fixed position,fixed orientation D)trans- acting,fixed position,fixed orientation E)cis- acting,variable position,fixed orientation

Question

Quizplus · Accepted Answer

Enhancers and silencers are cis-acting elements, meaning they are located on the same DNA molecule as the genes they regulate. They can have variable orientation (facing in different directions) and variable position (located at different distances from the gene they regulate) relative to the gene. Therefore, choice A - cis-acting, variable orientation, variable position - is the best fit.
