You are working for a biotechnology company that is trying to devise a competitive inhibitor of an enzyme required for the replication of the human immunodeficiency virus. you know the complete tertiary structure of the enzyme as well as the amino acids in the active site that are critical for the catalytic activity of the enzyme. based on what you have learned in this class, discuss how one might identify or design such an inhibitor.

How do antiviral drugs work? in your own words.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

1. mendel observed that pea plants had traits, such as color, that were either “one or the other,” never something in between. discuss the correlation between mendel’s factors, what they might be, and why pea plant traits come in one form or another—e.g., gray or dark red—rather than blended.
