Question
Classify each characteristic of gene regulation according to whether it applies to prokaryotes only, eukaryotes only, both, or neither Gene expression is usually controlled at the level of transcription initiation. The primary function of the cell's activities to external environment. Repressors are Regulatory proteins may Functionally related either inhibit or stimulate |genes are often grouped proteins that gene control is to ad bind to DNA and inhibitcurrent conditions in the transcription. into units called operons. translation. Major functions of gene Regulatory proteins act by binding to specific DNA Regulatory proteins always bind to DNA at sites that are within or In order to recognize the regulation include sequences, which affectsCOrrect binding sequence, regulatory proteins must Addition of ubiquitirn marks proteins for destruction. maintaining homeostasis and directing the the ability of RNA the 2 close to the gene being development of highly specialized cell types polymerase to bind to teunwind and separate t strands of DNA promoter regulated Gene expression may be regulated by altering chromatin structure Prokaryotes only Eukaryotes only Both NeitherExplanation / Answer
Functionally related gene are often grouped into unit called operon. This is the feature of prokaryote only where many gene regulated by one promotor.
Gene expression may be regulated by altering chromatin structure is a feature of eukaryote only because chromatin made up of histone and protein. chromatin present in eukaryote not in prokaryote.
Regulatory protein bind to specific DNA sequence which affect ability of RNA polymerase to bind with promotor. This is the feature of both prokaryote and eukaryote.
Regulatory protein may either stimulate or inhibt transcription. This present in both prokaryote and eukaryote. In peokaryote lac and trp operon regulatory protein help in gene regulation.
Gene expression control at level of transcription , this is the feature of eukaryote only.
