Which of the following statements correctly describes Chargaff’s contribution to the study of DNA?

• Chargaff’s work proved that DNA could be transferred from one organism to another.

• Chargaff showed that adenine and thymine were found in equal percentages in DNA, he also found this to be the case with cytosine and guanine

• Chargaff’s experiments conclusively proved that DNA was made of nucleotides

• Chargaff hypothesized that DNA was a double helix
