O cap, start codon, stop codon. enhancers, silencers, operator, promoter, polyadenylation signal. 5 prime end of RNA, GU-splice site, branch point-A, AG-splice site, polyadenylation signal. O repressors, activators, cap, start codon, stop codon. O promoters, GU-splice site, branch point-A, AG-splice site, polyadenylation signal. enhancers, silencers, promoters, polyadenylation signal. repressors, activators. attenuators, Shine-Dalgarno sequence, start codon, stop codon attenuators, activator binding site, promoter, operator, termination site start codon, stop codon.

one correct answer

Answer 1

repressors and activators.

Repressors and activators both are trans-acting elements, they are produced from the gene furthest from the gene they are regulating and control the gene expression by binding to the specific operator sequence of the gene. The cis-acting elements are always present in the vicinity or inside of the gene that has been regulated, for example, a promoter, operator, and attenuators.
