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.
Translating the code into an actual protein chain is complicated by the fact that individual amino acids won't interact with the messenger RNA chain. The amino acids have to be carried to the messenger RNA by another type of RNA known as transfer RNA-abbreviated to tRNA (as opposed to mRNA for messenger RNA). All of this is controlled by a ribosome-a hugely complicated structure involving protein molecules and yet another form of RNA (ribosomal RNA or rRNA).
