Homework Answers
1st option is correct answer
One codon codes for only 1 amino acid. Thus, it is unambiguous and specific.
The code has several levels of information, first the code for proteins but embedded in this code are features for reading it, editing it and finally for regulating it at several cellular levels.

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...

The genetic code is considered degenerate because most amino acids are encoded by at least two different codons. Some researchers have hypothesized that during evolution the genetic code has been optimized for its intended use in different organisms. Reseachers can study this by examining the relationship between the frequency with which an amino acid appears in all the proteins in an organism and the total number of codons for an amino acid. An optimized organism would use amino acids in...
