What is/are the possible genotype(s) of an individual who is lactose intolerant?

Phenylketonuria and alkaptonuria are both autosomal recessive diseases. If a person with PKU marries a person with AKU, what will the phenotype of their children be?

Why is it important that chyme from the stomach is delivered to the small intestine slowly and in small amounts?

Describe the location of hepatocytes in the liver and how this arrangement enhances their function.

Why are fatty acids better than glycogen for storing large amounts of chemical energy?

What is the genetic basis and phenotype for each of the following disorders (use proper genetic notation)? a. Edwards syndrome b. Patau syndrome c. Klinefelter syndrome d. Down syndrome

b. Compounds A, B, C, and D are known to be intermediates in the pathway for production of protein E. To determine where the block in protein-E production occurred in each individual, the various intermediates were given to each individuals cel Is in culture. After a few weeks of growth with the intermediate, the cells were assayed for the production of protein E. The results for each individuals cells are given in the following table. A plus sign means that protein E was produced after the cells were given the intermediate listed at the top of the column. A minus sign means that the cells still could not produce protein E even after being exposed to the intermediate at the top of the column. Denote the point in the pathway in which each individual is blocked.

Discuss how carbohydrates can be stored as fat.

A scientist discovers a virus encoding a Protein X that degrades a subunit of the elF4F complex. Knowing that this virus transcribes its own mRNAs in the cytoplasm of human cells, why would Protein X be an effective virulence factor?
