Now customize the name of a clipboard to store your clips. NATs have several advantages over other diagnostic tools, including rapid turnaround time, the ability to detect low levels of all known pathogens, the lack of dependence on the viability of the target microorganism, little influence of antimicrobial therapy on diagnostic sensitivity, and the ability to be automated. NUCLEOTIDE METABOLISM Mark Rush Nucleotides serve various metabolic functions. They are made up of repetitive subunits called nucleotides. Cirrhosis of liver is a complication of liver disease which is involving the loss of liver cells and the irreversible scarring of the liver. RNA not only stored and propagated genetic information, a role that is almost universally filled by DNA in current life forms, but it also realized and expressed this information, which in current life forms is mostly accomplished by proteins.
