AGGTATCGCAT is a sequence from the coding strand of a gene. What will be' the corresponding sequence of the transcribed mRNA?

Options

A. (a) UCCAUAGCGUA
B. (b) ACCUAUGCGAU
C. (c) UGGTUTCGCAT
D. (d) AGGUAUCGCAU

Answer

To determine the corresponding sequence of the transcribed mRNA from the given coding strand of DNA (AGGTATCGCAT), we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Coding Strand**: The given sequence is from the coding strand of DNA, which is 5' to 3' oriented. The sequence is AGGTATCGCAT.

2. **Understand Transcription**: During transcription, the DNA sequence is used to synthesize mRNA. The base pairing rules for transcription are as follows:
- Adenine (A) in DNA pairs with Uracil (U) in RNA.
- Thymine (T) in DNA pairs with Adenine (A) in RNA.
- Cytosine (C) in DNA pairs with Guanine (G) in RNA.
- Guanine (G) in DNA pairs with Cytosine (C) in RNA.

3. **Transcribe Each Base**:
- A (Adenine) → U (Uracil)
- G (Guanine) → C (Cytosine)
- G (Guanine) → C (Cytosine)
- T (Thymine) → A (Adenine)
- A (Adenine) → U (Uracil)
- T (Thymine) → A (Adenine)
- C (Cytosine) → G (Guanine)
- G (Guanine) → C (Cytosine)
- C (Cytosine) → G (Guanine)
- A (Adenine) → U (Uracil)
- T (Thymine) → A (Adenine)

4. **Combine the Transcribed Bases**: After transcribing each base, we combine them to form the mRNA sequence:
- The transcribed mRNA sequence will be: UCCAUAGCGUA.

5. **Final Answer**: The corresponding sequence of the transcribed mRNA from the coding strand AGGTATCGCAT is UCCAUAGCGUA.
