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.
ANSWER: Coupling of transcription and translation means that ribosomes bind to the mRNA and protein synthesis (translation) begins while the mRNA is still being synthesized (transcription).A cartoon of coupled transcription and translatio is shown below:NA polymerase moves along the DNA in a 5' to 3' direction, adding nucleotides to the 3'OH group of the growing RNA chain. The sigma-factor normally dissociates from the RNA polymerase core soon after transcription is properly initiated and chain elongation has begun.
