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 on the membrane of the nucleus and on the membrane of endoplasmic reticulum are called bound ribosomes. Chloroplasts in plant cells and mitochondria in all eukaryotic cells have ribosomes, which resembles prokaryotic ribosomes. In prokaryotes, ribosomes are scattered in the cytoplasm. Either eukaryotic or prokaryotic, ribosomes are made from protein and ribosomal RNA (rRNA).
