Question

Griffith's experiments advanced the study of genetics by proving that...

A. there is a chemical that contains genetic information that can be passed from one organism to another.
B. bacteria can make people sick by infecting them with a chemical that contains genetic information.
C. the bacteria that can make mice sick are the same bacteria that can be grown in culture dishes in a laboratory.
D. genetic information can be passed from parents to their offspring during sexual reproduction.

Answer 1

A. there is a chemical that contains genetic information that can be passed from one organism to another.

Hope this helps!

Answer 2

The correct answer would be A. there is a chemical that contains genetic information that can be passed from one organism to another.

Griffith proved that specific chemical is present in a cell which can pass from one organism to another. This chemical was responsible for the transformation of rough strain bacteria into smooth strain bacteria. He called this chemical as "transforming principle".

Today, we know this transforming principle as DNA (deoxyribonucleic acid) that is, a genetic material of almost all cells.
