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).
Ribosomes consist of two major subunitsâthe small ribosomal subunit reads the mRNA, while the large subunit joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of proteins.Eukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit. Their small subunit has a 16S RNA sub-unit (consisting of 1540 nucleotides) bound to 21 proteins.ach subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of proteins.
