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......
The proteins and nucleic acids that form the ribosome sub-units are made in the nucleolus and exported through nuclear pores into the cytoplasm. The two sub-units are unequal in size and exist in this state until required for use.ibosomes are found âfreeâ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome. Ribosomes have only a temporary existence.
