If T=40%, C=10% then G=? In a pollen cell

Options

A. 0.4
B. 0.1
C. 0.91
D. 0.2

Explanation

To solve the problem, we need to apply Chargaff's rules, which state that in a DNA molecule, the amount of adenine (A) is equal to the amount of thymine (T), and the amount of cytosine (C) is equal to the amount of guanine (G).

### Step-by-Step Solution:

1. **Identify Given Values**:
- Thymine (T) = 40%
- Cytosine (C) = 10%

2. **Apply Chargaff's Rule**:
- According to Chargaff's rule, the amount of adenine (A) is equal to the amount of thymine (T). Therefore, if T = 40%, then A = 40%.
- Similarly, the amount of guanine (G) is equal to the amount of cytosine (C). Therefore, if C = 10%, then G = 10%.

3. **Convert Percentage to Decimal**:
- Since the question asks for G in decimal form, we convert 10% to decimal.
- 10% = 10/100 = 0.1.

4. **Final Answer**:
- Therefore, the value of Guanine (G) is 0.1.

### Conclusion:
The answer is G = 0.1.
