Title: Microbiology Post by: BritneyB on Mar 6, 2012 1.) How does regulation by antisense RNA differ from that of riboswtiches?
2.) Describe how transcriptional attenuation works. What is actually being "attenuated"? Title: Re: Microbiology Post by: duddy on Mar 6, 2012 1.) How does regulation by antisense RNA differ from that of riboswtiches? Antisense RNA is a single-stranded RNA that is complementary to a messenger RNA (mRNA) strand transcribed within a cell. Antisense RNA may be introduced into a cell to inhibit translation of a complementary mRNA by base pairing to it and physically obstructing the translation machinery. In molecular biology, a riboswitch is a part of an mRNA molecule that can directly bind a small target molecule, and whose binding of the target affects the gene's activity. Thus, an mRNA that contains a riboswitch is directly involved in regulating its own activity, in response to the concentrations of its target molecule.
