Question 18 (1 point)
The existence of 64 different codon triplets and 20 different amino acids is reconciled in the cell by:
Question 18 options:
failure to use most of the available triplets as mRNA codons.
wobble in which the 3' nucleotide of the anticodon can pair loosely with the codon.
wobble in which the 5' nucleotide of the anticodon can pair loosely with the codon.
an aminoacyl-tRNA synthetase that recognizes over 60 different tRNAs.
the cell has not figured this one out yet.

Explanation / Answer
Answer for Q17 : The correct option is B (The structure of the side chain or R group)
Information : All amino acids contains an hydrogen atom, amino group and carboxyl groups which are present in all the amino acids. However, amino acids differs from each other in their side chain or the functional group (R groups) which is also attached to alpha carbon atom. These R groups vary in structure, size, and electric charge, and which influence the solubility of the amino acids in water.
