Question

chargaff found that the proportion of adenine, guanine, cytosine, and thymine varied from organism to organism. How dos chargaffs work support the idea that Dna is the molecule of inheritance

Answer 1

Chargaff's work supports the idea that DNA is the molecule of inheritance because it showed that the proportions of the four nucleotides in DNA vary from organism to organism. This suggests that the sequence of nucleotides in DNA is responsible for the differences between organisms, and that this sequence is passed down from generation to generation. This is consistent with the idea that DNA is the molecule of inheritance.
