By the 1930s, genes were known to be on chromosomes. What were they made of?

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

What did most scientists originally think about proteins compared to DNA?

• Proteins were simple, and DNA was complex.

• Both proteins and DNA were equally complex.

• Proteins were complex, and DNA seemed too simple.

• DNA was complex, and proteins were too simple.

What did experiments eventually show about DNA?

• DNA is a protein.

• DNA is the carrier of genetic material.

• DNA is a type of sugar.
