Question
Chapter 14, Problem 1U
Summary Introduction
To determine:
Results obtained from the Griffith’s experiments using live and heat killed pathogenic bacteria.
Introduction:
Transformation of DNA is the process by which DNA of the host cell or the infecting cell is changed by the incorporation n of an outside DNA that is of some other organism. This process was discovered by Frederick Griffith, when he was trying to make vaccine against influenza virus. He carried out his experiment in mouse.
