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.
The second is conjugation, which allows for the transfer of DNA through a structure called a pilus from one cell to another. Bacterial conjugation can be likened to the mating rituals of other species in the sense that it requires direct cell-to-cell contact and involves the exchange of genetic material. The final mechanism of horizontal gene transfer is transduction, which uses bacteria viruses to transfer DNA from one cell to another. Transduction does not require direct contact like conjugation. And unlike transformation, it needs a third party to help transfer the gene.
