Homework Answers
The direction of protein synthesis is from amino or N terminus
to carboxy or C terminus. Since the fourth codon is GGG which codes
for glycine, so the fourth amino acid from the N-terminus is
glycine.
Option B is correct
Option A is wrong ( GGG is at fourth position from the N-terminus not at the third position).
Option C is wrong ( Direction of protein synthesis is from N terminus to C terminus).
Option D is wrong (Position of GGG is fourth from the N terminus not from the C terminus).

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...

3. What are the “translator” molecules that recognize a codon in the mRNA and deliver the correct amino acid? 6. If each amino acid was encoded by a single codon, what is the minimum number of amino-acyl tRNA synthetases required for translation? 7. Looking at the codon table, if there was a unique aminoacyl-tRNA synthetase required for each anticodon, what is the minimum required? 9. If an aminoacyl-tRNA synthetase recognized any nucleotide (purine or pyrimidine) in the 5’end of the anticodon,...
