Amino acids/peptides attached to the amino acyl tRNA at the P site are transferred to amino acids at the A site, followed by translocation. C. Empty TRNAS are immediately released from the ribosomes D. The E site is always empty after translocation to receive incoming empty TRNAS. E. The anticodon binding to the codon is stringent, i.e. there must be complete complementary base-pairing between the bases in the codon and anticodon before translation can proceed.arrow_forwardSickle cell disease (SCD) is a group of inherited disorders.
