Question

Recall that a series of experiments using heat-inactivated S strain and live R strain of S. pneumonia supported the hypothesis that DNA was the carrier of hereditary information. Let’s imagine that in a parallel universe, these were the results. According to these data, which molecule would likely be the carrier of hereditary information? Explain in a sentence or two how you came to this conclusion. (1 pt)

Explanation / Answer

According to the above results LIPID would be likely hereditary material.

reason: Similar as in griffith experiment there is something that transferred from the S train to R stain that is why the mouse do not dies and the Live strain do not recovered. while in other cases there is no transfer of information in other cases.
