Question
Chapter 33, Problem 5P
Interpretation Introduction
Interpretation:
The role played by the protein containing the domains for 5-methylcytosine should be determined.
The place on DNA where this domain of the protein would bind should be determined.
Concept introduction:
DNA methylation is the process of adding methyl groups to the bases of the DNA. This process is catalyzed by the enzyme methyltransferase. Methylation of DNA does not change the DNA sequence but can change the activity of DNA. When methylation occurs at the promoter region of DNA, then the gene becomes repressed.

proteins. Which of the following will tell you whether a protein would be found in the lumen of the ER?
A. You run a hydropathy plot an look for hydrophobic peaks that span 20-30 amino acids
B. You isolate microsomes and see whether the proteins are inserted into the membrane of the microsome
C. You run a hydropathy plot an look for a lack of hydrophobic peaks that span 20-30 amino acids
O D. You do in vitro translation of each protein in the presence or absence of microsomes and look to see whether there is a size change in the presence
of microsomes.
Leaderless. The MRNA for the A repressor begins with 5'-AUG-3',
5'-AUG-3', which encodes the methionine residue that begins the
protein. What is unusual about this beginning? Would it cause the
MRNA to translate efficiently or not?
