How is a tRNA able to recognize its proper mRNA codon?
A) Hydrogen bonding between the ribosomal subunits and the mRNA creates the proper active site conformation to allow tRNA binding.
B) Complementary hydrogen bonding between tRNA and mRNA promote binding.
C) The amino acid on the tRNA recognizes the mRNA codon through hydrogen and ionic bonding.
D) Ionic bonds between the tRNA and the active site of the ribosomal subunits promote binding to the mRNA.
E) Appropriate shape of the tRNA allows it to fit onto the extended mRNA strand.
