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.
A tRNA can now come into this site if it has the anticodon that is complementary to the next codon on the mRNA (Figs. 20,21). The ribosome will then form the peptide bond between the third and second amino acids and kick off tRNA number two (Fig. 21). The third tRNA now binds a chain of three amino acids.). Peptide bonds are strong covalent bonds which keep the amino acids connected during and after translation. The tRNA at the âPâ site has now accomplished its task by bringing in the first amino acid. This tRNA will then move off the ribosome (Fig.
