Question

(iii) Write the conclusion they arrived at the end of their experiment.

Hint:

Hershey and Chase demonstrated conclusively that DNA, not protein, is the hereditary material in cells.

Answer 1

Hershey and Chase concluded that DNA, not protein, is the genetic material responsible for heredity. \begin{itemize} \item Observation: $^{32}$P (DNA) entered bacterial cells during phage infection, while $^{35}$S (protein) remained outside. \item Impact: This finding shifted the focus of molecular biology research toward DNA’s structure and role in heredity, paving the way for key discoveries like the double-helix structure. \end{itemize} % Quick tip
