2023 HESI A2 BIOLOGY EXAM PREP Q&A 1. 1. QUESTION A clinical researcher administered a pill with no therapeutic value to his subject. Which of the following best describes this treatment? o Experimentation o Placebo o Evaluation o Double-blind A placebo prevents the test subjects from knowing whether they are being given the real therapeutic drug or not. This helps the examiner understand the true effects of the drug. Experimentation involves a set of procedures used to test a particul...

DNA Composition • DNA is often viewed in its double helix formation, which resembles that of a twisted ladder. • The ‘rungs’ of the ladder are composed of nitrogenous bases, of which there are four types: adenine (A), guanine (G), thymine (T), and cytosine (C). • Adenine and guanine are purines • thymine and cytosine are pyrimidines. • Each nitrogenous base has a unique structure • Each base is chemically linked to the sugar deoxyribose. • A base plus deoxyribose is cal...
