Question

Quizplus · Accepted Answer

In the classic experiment by Griffith, evidence of the action of a hereditary biomolecule was identified by transformation (phenotypic change) of the R strain by S strain biomolecules. When heat-killed S strain bacteria were mixed with live R strain bacteria, the R strain bacteria were transformed into the S strain phenotype. This transformation was due to the uptake of genetic material (DNA) from the dead S strain bacteria by the live R strain bacteria. This experiment provided the first evidence for the role of DNA as the hereditary material.
