'The main symptom of detachment is a large blank area in your vision that won't go away, which may be associated with flashing lights or a general fuzziness.
The three-base sequence on a tRNA molecule is known as an anti-codon. This matches up with the codon (another 3-base code) on the mRNA to ensure that the correct amino acid is added to the chain (protein) being created.
1 Completed in the cytoplasm when tRNA enters ribosomes to read mRNA codons and link together amino acids (translation). 2  DNA helicase (enzyme) uncoils the DNA molecule. 3  RNA polymerase (enzyme) binds to a region of DNA called the promoter which has the start codon TAC to code for the amino acid methionine.
