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.
Messenger RNA (mRNA) is the RNA that carries information from DNA to the ribosome, the sites of protein synthesis (translation) in the cell. The coding sequence of the mRNA determines the amino acid sequence in the protein that is produced.ransfer RNA (tRNA) is a small RNA chain of about 80 nucleotides that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation.
