Chapter 23, Problem 5STP

Interpretation Introduction

Interpretation:

The % T of sample IV using table 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 5STP

A is the correct option.

Explanation of Solution

The given table is,

From the table, the given percentage of adenine base in sample IV is 28.4%. The percentage of T and A is the same. Because of this reason, T and A form bonds with each other.

So, percentage of A and T must be same, i.e., 28.4%. So, A is the correct option.

Conclusion

The percentage of A and T must be same, so option B, C and D are incorrect.
