Chapter 12.1, Problem 2LO
Summary Introduction
To state: The questions that Griffith’s transformation experiment, Avery’s contribution to Griffith’s work, and the Hershey–Chase experiments had been addressed.
Introduction: DNA or deoxyribonucleic acid carries hereditary information from one generation to another. After several experiments, scientists have found evidence that claims that DNA is the hereditary material that passes on the genetic information from one generation to the next. DNA can be transferred through sexual or asexual reproduction. Proteins are products that are obtained from DNA after transcription and translation.
