The correct Answer is:
To solve the problem of determining the nucleotide sequence of mRNA transcribed from a given DNA sequence, we will follow these steps: ### Step-by-Step Solution: 1. **Identify the DNA Sequence**: The given DNA sequence is ATACG. 2. **Understand Base Pairing Rules**: During transcription, the base pairing rules are as follows: - Adenine (A) pairs with Uracil (U) in RNA (instead of Thymine (T) in DNA). - Thymine (T) pairs with Adenine (A). - Cytosine (C) pairs with Guanine (G). - Guanine (G) pairs with Cytosine (C). 3. **Transcribe the DNA Sequence**: Using the base pairing rules, we will transcribe the DNA sequence ATACG into mRNA: - A (from DNA) pairs with U (in mRNA). - T (from DNA) pairs with A (in mRNA). - A (from DNA) pairs with U (in mRNA). - C (from DNA) pairs with G (in mRNA). - G (from DNA) pairs with C (in mRNA). 4. **Write the mRNA Sequence**: Following the transcription, we get the mRNA sequence: - A → U - T → A - A → U - C → G - G → C Therefore, the mRNA sequence is **UAUGC**. 5. **Conclusion**: The nucleotide sequence in mRNA transcribed from the DNA sequence ATACG is **UAUGC**.
