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.ukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit. Their 40S subunit has an 18S RNA (1900 nucleotides) and 33 proteins. The large subunit is composed of a 5S RNA (120 nucleotides), 28S RNA (4700 nucleotides), a 5.8S RNA (160 nucleotides) subunits and 46 proteins.
