1 A diagnostic test is any kind of medical test performed to aid in the diagnosis or detection of disease. 2  Diagnostic tests can also be used to provide prognostic information on people with established disease. 3  Processing of the answers, findings or other results.iagnosis is a major component of the procedure of a doctor's visit. From the point of view of statistics, the diagnostic procedure involves classification tests.
All of them make these proteins in the same wayâmessenger RNA dictates the precise ordering of amino acids (bound to tRNAs) at an organelle called the ribosome. Not only are ribosomes of interest because proteins are made there, the structure of ribosomes offer a tantalizing glimpse into early life. The original function of the ribosome might have been RNA replication using trinucleotide RNA subunits (Martin, 2002a).
The ribosomes link amino acids together in the order that is specified by the messenger RNA molecules. The ribosomes are made up of two subunits-a small and a large subunit. The small subunit reads the mRNA while the large subunit joins the amino acids to form a chain of polypeptides. They are found scattered in the cytoplasm and some are attached to the endoplasmic reticulum. 2  When the ribosomes are bound to the ER there are known as the rough endoplasmic reticulum. 3  The bound and the free ribosomes are similar in structure and are invloved in protein synthesis.
