Question

Which one of the following discoveries involving DNA happened first?

A. Avery discovered that DNA was responsible for storing and passing information through generations.
B. Griffith learned that a chemical changed harmless cells into harmful cells.
C. Chargaff discovered that base pairing was consistent in samples of DNA.
D. Hershey and Chase used bacteriophages to confirm that DNA was the genetic material in genes.

Answer 1

The answer is (A.) Avery discovered that DNA was responsible for storing and passing information through generations.

Avery is correct. DNA serves as a storage if genetic information and passed it through generations. The DNA strands replicate and each strand serves as a template for duplication during the cell division. Therefore, DNA is the reason for biological continuity.
