Theoretically it is the Chargaff's rule which entails that the ratio of purines and pyrimidines are 1. So following that rule you can solve this question.

G (purine) = C (pyrimidine) and

A (purine) = T (pyrimidine)

So G + C  would be 28% and hence

A +C would be 72% i.e. 36% each.

Please note that their are certain modified bases besides these four are also there including methyl Cytosine, Methylated Adenine. But htese modification does not violate the Chargaff's rule and they follow standard Watson Crick base pairing.

What role does iodine play within the thyroid?
lesantik [10]
Iodine it is an element that is required for the thyroid gland to produce thyroid hormones.
The body does not produce iodine on its own so it needs to come from dietary sources like eggs, prunes bananas, shrimp, cod, etc or you can take supplements of iodine.
When you consume iodine it quickly absorbed and enters into your bloodstream and thenyour thyroid that has tiny cells that capture the circulating iodine and takes in and oxidizes it so it can begin to be used to create (T3) and (T4 which are thyroid hormones.
