Griffith's Theory

Griffith's theory, originally developed by Frederick Griffith in 1928, demonstrates how bacteria can transfer genetic information. He showed that non-virulent bacteria could become virulent when they absorbed DNA from dead virulent bacteria. This process, known as transformation, revealed that genetic material could be exchanged between organisms, leading to changes in traits. Griffith's findings laid the groundwork for modern genetics, highlighting how DNA is vital for inheritance and enabling the understanding of how traits are passed on and how bacteria can adapt and evolve.
