If the rip is at the top, with gravity, the retina can be pulled off in less than 24 hours; with a rip at the bottom, that process can take weeks. '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.
The first codon is AUG, called a start codon. It also codes for the amino acid Met (methionine). So tRNA with the anti-codon sequence of UAC carrying the amino acid Met bonds to the mRNA codon. Another tRNA bonds to the next codon in the next groove with the next respective amino acid.
