Interpretation:
The number of molecules of adenine in one molecule of Sample II needs to be determined.
Concept introduction:
DNA stands for deoxyribonucleic acid and RNA stands for ribonucleic acid. DNA includes four bases such as adenine (A), guanine (G), cytosine (C), and thymine (T). RNA consists of four bases: adenine, cytosine, uracil, and guanine.
Answer to Problem 7STP
Option C is the correct option.
Explanation of Solution
We know that 32.5% of bases is equal to 402. So, one can calculate the total number of bases by using the following formula,
Hence, the total number of bases is
If C = G, then percentage is equal to 32.5% and total percentage after adding is 65%. The percentage left over is 32.5% composed of A and T. By this it can be concluded that 17.5% is A and 17.5% is T.
The number of molecules of adenine is determined as follows,
216 molecules of adenine are there in one molecule of Sample II.
