The growing protein exits the ribosome through the polypeptide exit tunnel in the large subunit. Elongation starts when the fMet-tRNA enters the P site, causing a conformational change which opens the A site for the new aminoacyl-tRNA to bind. This binding is facilitated by elongation factor-Tu (EF-Tu), a small GTPase.rokaryotic translation is the process by which messenger RNA is translated into proteins in prokaryotes.
In Tahiti, food is traditionally cooked in an ahimaa or oven, which is a hole dug into the ground. In here the food is placed, usually wrapped in banana leaves, and the hole is then covered with sand to make it airtight.
