Question

by using enzymes that destroyed dna, rna, or protein, avery and colleagues were able to determine which of the three molecules was required to transform bacterial cells. question 2 options: true false

Answer 1

The statement is true; Avery, MacLeod, and McCarty's experiments using enzymes to degrade DNA, RNA, and proteins showed that DNA is the molecule required for the transformation of bacterial cells.

Step-by-step explanation:

The statement that Avery and colleagues used enzymes to determine which molecule was necessary to transform bacterial cells is true. Scientists Oswald Avery, Colin MacLeod, and Maclyn McCarty conducted experiments in 1944 using specific enzymes that would degrade DNA, RNA, or proteins to understand the nature of the transforming principle in bacteria. In their systematic elimination study, they demonstrated that only when DNA was destroyed was the transformation ability lost, leading to the groundbreaking conclusion that DNA is the molecule responsible for heredity. This discovery paved the way for future research in genetics and molecular biology, including the later work by Hershey and Chase that further confirmed DNA as the genetic material.
