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. Crushed rock, on the other hand is a little bit larger in diameter around 1/2 to 1 inch.ize and Appearance. The main difference between these two types of gravel is the size of the rocks.

Dimensions and Appearance. The main difference between pea gravel and crushed stone are their sizes. Pea gravel is generally 1/8â³ to 3/8â³ in size or about the size of pea, hence the name âpeaâ gravel. Crushed stone is available in sizes from 1/2â³ to about 4â³.There is a category of crushed stone known as stone dust or screenings and it is just as it says, dust.he main difference between pea gravel and crushed stone are their sizes.
