If the sequence of bases in one of the DNA strand is A G G A G A A, then the sequence of bases in the other complementary strand of DNA would be

Options

A. C C T T C T T
B. T C T C T C C
C. T C C T C T T
D. C C T C T C T

Answer

To determine the sequence of bases in the complementary DNA strand, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given DNA Strand**: The sequence provided is A G G A G A A.

2. **Understand Base Pairing Rules**: In DNA, the base pairing rules are as follows:
- Adenine (A) pairs with Thymine (T)
- Guanine (G) pairs with Cytosine (C)

3. **Pair Each Base**: Using the base pairing rules, we will find the complementary base for each base in the given strand:
- A pairs with T
- G pairs with C
- G pairs with C
- A pairs with T
- G pairs with C
- A pairs with T
- A pairs with T

4. **Write Down the Complementary Sequence**: Now, we can write the complementary sequence based on the pairs:
- A → T
- G → C
- G → C
- A → T
- G → C
- A → T
- A → T

Therefore, the complementary strand will be: T C C T C T T.

5. **Final Answer**: The sequence of bases in the complementary DNA strand is T C C T C T T.
