A virus has been discovered. The virus has no envelope and consists of a helical capsid surrounding its dsDNA genome. During assembly, the pac site of the genome ensures that it is properly packaged by the capsomeres. Which of the following amino acids is/are expected to be on the capsomere domain that interacts with the pac site? A. lysine B. methionine C. glycine D. arginine E. A and D Answer: A and D Explanation: DNA has a negative charge, so positively charged amino acids, such as...

Long Term Potential (LTP) can last for days or weeks in dissected tissue; it is thought to represent one of the fundamental processes by which memories are stored and learning takes place. To achieve LTP, which learning strategies should you, as a student, employ? I. Taking active notes in lecture. II. All-night cram sessions the night before an exam. III. Pre-skimming the readings from the textbook. IV. Carefully reading the entire textbook and taking detailed notes. V. Reviewing the mater...
