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.
tRNA. 1  Transfer RNA. 2  Single stranded molecule containing 80 nucleotides in the shape of a cloverleaf. 3  Carries amino acids in the cytoplasm to ribosomes for protein assembly. 4  Three bases on tRNA that are complementary to a codon on mRNA are called anticodons (e.g. codon-UUA; anticodon-AAU).
