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 ribosome (/ËraÉªbÉµËzoÊm/) is a large and complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain.rokaryotes have 70 S ribosomes, each consisting of a small (30S) and a large (50S) subunit. Their small subunit has a 16S RNA subunit (consisting of 1540 nucleotides) bound to 21 proteins. The large subunit is composed of a 5S RNA subunit (120 nucleotides), a 23S RNA subunit (2900 nucleotides) and 31 proteins.
