Clues

  • acts as the adapter (8, 3)
  • complex forms, initiator tRNA charged with methionine + the small ribosomal subunit bound to mRNA triggers beginning of translation (10)
  • consists of triplets of nucleotides (7, 4)
  • more than 1 ribosome moves along mRNA at one time, multiple copies of same protein made from single mRNA (8)
  • mRNA meets charged tRNAs at ribosome, two subunits: small + large, 4 sites: E, P, A, T (8)
  • presence of stop codon in A site of ribosome, completed protein released (11)
  • ribosome moves along mRNA in 5'-3' direction, polypeptides grow from N terminus, charged tRNA's bring amino acids to the ribosome sequentially, specificity provided by the anticodon interaction + the accuracy of aminoacyl-tRNA synthetases (10)
  • ribosomes, tRNA's, activating enzymes + mRNA (11, 8)
