When a new food product is being analyzed for nutritional content, the food will be subjected to hydrolysis in the lab. The end products are analyzed to determine, for example, fat and sugar content. Suppose a lab is analyzing a new product that claims
to be fat free. After the hydrolysis of the product is complete, the examiners find glucose, glycerol, fatty acids, and amino acids. Is this product free of fat? Justify your answer.
What will be an ideal response?
This product is not fat free because it contains fatty acids. It also contains glycerol. Because fats are composed of a glycerol molecule and three fatty acids, this product contains all components found in fat.

What new technique or technology may revolutionize the way in which cell biologists alter the genomes of cells and organisms?
A) genome editing B) homologous recombination C) RNA-mediated interference D) recombinant DNA technology E) next-generation sequencing
Denaturation of protein X yields two subunits, A (MW 8,000) and B (MW 20,000). In order to understand the quaternary structure, a crosslinking experiment was performed with cell extracts
Analysis of the crosslinking products by SDS-PAGE showed four bands of the following molecular weights: 7,800, 19,500, 39,000, and 48,000 . This data suggests that protein X functions in vivo as: A. a dimer. B. a trimer. C. a tetramer. D The results are inconclusive.
