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......
Ribosomes in these organelles are more like ribosomes found in bacteria with regard to size. The subunits comprising ribosomes in mitochondria and chloroplasts are smaller (30S to 50S) than the subunits of ribosomes found throughout the rest of the cell (40S to 60S).
