Answer to Question 1

A

Answer to Question 2

Nutrients consumed within a diet can both positively and negatively affect the body by activating or silencing gene expression. One way they do this is by changing the methylation at the start of a specific gene, which turns the gene on and off like a switch. By turning on or off the ability of the cell to make mRNA copies of itself, it will alter protein synthesis of a given protein. When the DNA for a gene coding for a specific protein is turned on, mRNA expression will increase, and subsequently levels of that protein will increase. When the DNA for that gene is turned off, mRNA expression will decrease, and the levels of that protein will decrease.
