Diagnostic tests measure students' understanding of a subject area or skills base. Teachers typically administer diagnostics for reading and math skills, using the results to provide remedial instruction or place students within appropriately leveled classes.hildren take the test individually or in groups; some reading diagnostics are computer based while others require interaction with a test proctor. Such tests are designed to pinpoint at what grade level children are reading based on their mastery of phonics, blending, word recognition and text comprehension.
In protein synthesis or translation, mRNA along with tRNA and ribosomes work together to produce a protein. Protein synthesis is accomplished through a process called translation. After DNA is transcribed into a messenger RNA (mRNA) molecule during transcription, the mRNA must be translated to produce a protein. In translation, mRNA along with transfer RNA (tRNA) and ribosomes work together to produce proteins.
The translation of RNA to protein is different than the synthesis of RNA from DNA (transcription). When the DNA was transcribed into RNA, one base of DNA corresponded to one base of RNA, this 1 to 1 relation is not used in the translation to protein. During this translation, 1 amino acid is added to the protein strand for every 3 bases in the RNA. So a RNA sequence of 48 bases codes for a protein strand of 16 amino acids. A certain combination of 3 bases always gives the same amino acids, so we can put the translation into a table (see below).
