Homework Answers
# The mutation changed the codon but the new codon codes for the same aminoacid.
Codons has degeneracy that means the same aminoacid can be coded by different codons. Therefore, the mutation would bring another codon that codes for the same ainoacid.
# Protein ubiquitination, which targets the protein for degradation.
Regulation of gene expression at DNA level is the earliest one. Regulation at mRNA level is the second one and the regulation at protein level would be the last one.
The order of gene expression will be transcription and translation.

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...

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
