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).
1 Ribosomal RNA (rRNA) is a component of cell organelles called ribosomes. 2  A ribosome consists of ribosomal proteins and rRNA. 3  Ribosomes are typically composed of two subunits: a large subunit and a small subunit. 4  Ribosomal subunits are synthesized in the nucleus by the nucleolus. The amino acid sequences are joined together to form a protein. 2  Transfer RNA is shaped like a clover leaf with three hairpin loops. 3  It contains an amino acid attachment site on one end and a special section in the middle loop called the anticodon site. 4  The anticodon recognizes a specific area on mRNA called a codon.
