Erwin Chargaff's work on the composition of nucleic acids began in 1944. His findings, which later became known Chargaff's rules, detail the specific pairings that occur in double-stranded DNA molecules.
According to one of Chargaff's rules, a section of DNA molecule that contains 50 base pairs and has 15 adenine
bases must also contain -
A
15 guanine bases
B
15 cytosine bases
C 15 thymine bases
D 15 uracil bases
1-35
