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 are the only organelles which are conserved between all eukaryotic and prokaryotic organisms. As the sites of protein synthesis, they are essential parts of the cell. In mammals, ribosomes are composed 4 types of rRNA and around 80 different proteins. In mammalian cells, ribosomal proteins can compose up to 15% of a cellâs total protein and 7-9% of the mRNAs which are made.
