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.
Size and Appearance. The main difference between these two types of gravel is the size of the rocks. Pea gravel, as its name implies, is small. Generally the stones are around 1/4th of an inch in diameter.They have a smooth, rounded surface and come in many different soft colors such as light blue, light red and beige.
