How were the researchers able to independently measure dna synthesis and rna synthesis?

DNA and RNA synthesis

Explanation:

Thymidine is a nucleoside building block for DNA, but not RNA, whereas uridine is a nucleoside building block for RNA, but not DNA

Both DNA and RNA are types of nucleic acids DNA evolved from RNA and helps in the storage,expression and transmission of genetic information(does not act as an enzyme) and follow Chargaff's ruleChargaff rule states that purines(adenine and guanine) will always be equal to pyrimidines(cytosine and thymine)RNA evolved first,structurally and functionally more diverse than DNA and act as an enzymeRNA does not follow Chargaff's ruleUracil is found in RNA(in place of thymine)

Ihaven't done that yet, so no idea,but this is not the right place to ask
