We may not be able to match the olfactory feats of bloodhounds, but we can, for example, âtrackâ a trail of invisible human footprints across clean blotting paper. The human nose is in fact the main organ of taste as well as smell.
Ribosome. an intracellular particle concerned with protein biosynthesis that is found in the cells of all living organisms (bacteria, plants, and animals); each cell contains thousands or tens of thousands of ribosomes. nucleic acid nucleic acid,any of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis......
Chemical and microscopic analysis shows how the structures of mitochondrial and bacterial ribosomes share more similarities with each other than with ribosomes in eukaryotic cells. Ribosomes found in the cytoplasm of eukaryotic cells are 80S in size while ribosomes found in bacteria and mitochondria are 70S in size (3).
