<span>One extensive membrane bound structure serves as the site of origin for protein secretions and enzymes used in other organelles. The name of this membrane bound organelles in eukaryotic is the ribosome. </span><span>In the cytoplasm, ribsomal RNA (rRNA) and
protein combine to form a nucleoprotein called a ribosome. The ribosome
serves as the site and carries the enzymes necessary for protein
synthesis. The ribosome attaches itself to m-RNA and provides the
stabilizing structure to hold all substances in position as the protein is synthesized.
Several ribosomes may be attached to a single RNA at any time. <span> </span></span>

There probably would've never been life on Earth. The dinosaurs wouldn't have died out as quickly then, they probably would've eventually all died out at some point, but that would've taken a long time. The Age of Mammals would've been halted for a long time. <span />
