There is always a 1 to 1 correspondence between the number guanines (g) and the number of cytosines (c) in a dna molecule. the same is true of the relationship between adenine (a) and thymine (t). of course professor floop knows this. he analyzed a strand of dna and determined the amounts of c and g it contained. if the molecule was 22% g, what was the percentage of a, assuming that dna only contains g, c, a, and t

the strand contains 28% of adenine.

Step-by-step explanation:

We have only four components, and we only know one of them:

Cytosine has a relation 1 to 1 with G, therefore the strand must contain the same amount of C as it posses G:

Therefore:

This is because the strain only contains those 4 components.

since A and T have also a 1 to 1 relation, we can state that A = T in quantity.

So:

answer: ok
