DNA-binding proteins can block transcription. DNA binding proteins can activate transcription. DNA-binding proteins can catalyze transcription. All of the listed responses are …
WebRNA plays a significant role in regulating a diverse set of cellular processes in all life. One of the recently discovered forms of genetic regulation by RNA is the riboswitch. This ribonucleic acid sequence is most often found at the 5' end of the untranslated region of bacterial mRNA. The hallmark of this regulatory element is the ability of the RNA to bind to …
