Iodine, or more accurately iodide (I-), is avidly taken up from blood by thyroid epithelial cells, which have on their outer plasma membrane a sodium-iodide symporter or "iodine trap". Once inside the cell, iodide is transported into the lumen of the follicle along with thyroglobulin.
Explanation:
Acid fast stain is used to stain the bacteria of the genus Mycobacteria, because they contain large amounts of impermeable wax-like sbstances, which do not allow gram stain to penetrate the cells. Gram stain however, can penetrate the other bacteria with varying amounts of polysaccharides and lipopolysaccharadies in their cell walls, and thus can differentiate between them, For Acid fast stain, it would be difficult to differentiate between the gram positive and negative cells, and therefore, it is not used for this differential purpose, but to identify the Mycobacterim only.
Macromolecules in the mammals are of three different types, namely the carbohydrates, proteins, and the nucleic acids. Among these macromolecules, the nucleic acids are capable of self-replication. These encode the genetic information of the organism, and plays a vital role in carrying out an array of different functions of the body. One example of such nucleic acid is the RNA, or the Ribonucleic Acid.
