Many proponents of marijuana claim that it has no lasting effects on the body. Science has proven that this is not true. Marijuana can impact many systems in the body, including the eyes. In fact, marijuana is often touted as a treatment for patients with glaucoma.
The common thinking is that transcriptionâtranslation coupling is a means for the cell to prevent accumulation of non-functional transcripts in the cytoplasm (;), and hence that it is functionally analogous to nonsense-mediated mRNA decay that occurs in eukaryotic cells (; ;).everal co-transcriptional activities involving RNA as the substrate serve to prevent the occurrence of R-loops, and the coupling of transcription to translation in the bacteria may be seen as a special instance of such a co-transcriptional activity.
Excitation-contraction coupling refers to a somewhat abstract description of the processes involved in muscle contraction. The musculoskeletal system is intricately intertwined with the nervous system, allowing muscle contraction and movement to occur through communication with sensory and motor neural pathways.ction potential occurs when there is a sudden and sharp change in the potential difference across the membrane of a nerve cell that is propagated along the length of the cell. Touching a hot surface is an example of excitation-contraction coupling. View slideshow of images above. Watch the Did-You-Know slideshow.
