Answer:
Bacterial cells are prokaryotic cells
Explanation:
Answer:
The correct answer is B) DNA has 30% thymine and 20% cytosine.
Explanation:
We use the Chargaff Law, where:
A + G = C + T (sum of pure bases A and G, is equal to pyrimidines C and T) and, A = T, C = G.
A + G = 30% + 20% =50% = C+ T
Thus:
A = 30% = T
G = 20% = C
