Answer:
In an organism, amount of adenine base is equal to amount of thymine base. And amount of guanine base is equal to amount of cytosine base.
Step-by-step explanation:
The relative proportions of DNA bases in all the organisms with double stranded DNA as genome follow Chargaff's rule. Accordingly, total number of purine bases (adenine + guanine) in DNA is always equals to total number of pyrimidine bases (cytosine + thymine). Since adenine pairs with thymine and guanine pairs with cytosine, number to adenine base is equal to that of thymine and total amount of guanine base is equal to that of cytosine base.
