Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...

Question 10 (10 pts) Peptides are biological oligomers formed by condensing multiple amino acids into an amide backbone. Although this amide backbone is common to all peptides, the so- called 'side-chan' groups attached to this backbone vary depending the amino acids used in the condensation reaction. Shown below are four different tetrapeptides (so-named because they are the products of the condensation of four amino acids). Based on their structures, predict the order of elution that one might expect if separating...
