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.

What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
