DNA, RNA Discovery Quiz

Welcome to the science electronic classroom of the 21st century. This quiz will test your knowledge of how Griffith's bacterial experiments showed that a hereditary factor was involved in transformation. How Avery's experiments led his group to conclude that DNA is responsible for transformation in bacteria. Decribe three parts of a nucleotide. Summarize the role of covalent and hydrogen bonds in the structure of DNA. This quiz will allow unlimited number of attempts and generate new questions every attempt. I wish you well on the quiz. Good Luck!
