<span>Avery Identified through a qualitative test that DNA was present. Through a chemical test he found that the make up was DNA. Through enzyme testing Avery found that only DNA degradation stopped transforming.</span>
I believe it would be option A. If it still doesn't answer your question, don't hesitate comment below. :)
Answer:D, how relatively little genetic change could lead to the significant differences we see between ourselves and chimps. 3 mya-2 mya. You inherited from your mom both her crooked nose and her recipe for chocolate chip cookies (both favorable traits).

Answer:
Yes, if there is a mutation in the operator of the lac operon in a cell such that the lac repressor always stays bound to the operator. If lactose is added to the cell, the lac repressor loses its ability to bind DNA. It clear off the operator, clearing the way for RNA polymerase to transcribe the operon.
