Question

If a DNA strand with the following sequence was transcribed to RNA, what would be the resulting strand?
ACG TAG CCA
*
20 points
UGC AUC GGU
TGC ATC GGT
CAG UCC GGU
TAG TUC GAU

Answer 1

To determine the resulting RNA strand from the DNA sequence given (ACG TAG CCA), we need to transcribe the DNA sequence into RNA. The transcription process involves replacing thymine (T) in DNA with uracil (U) in RNA, while the other bases (A, C, G) remain the same.

Here’s the transcription process step-by-step for the given DNA sequence:

1. A (Adenine) in DNA corresponds to U (Uracil) in RNA.
2. C (Cytosine) in DNA corresponds to G (Guanine) in RNA.
3. G (Guanine) in DNA corresponds to C (Cytosine) in RNA.
4. T (Thymine) in DNA corresponds to A (Adenine) in RNA.

Now let's transcribe each base from the DNA sequence:

- A → U
- C → G
- G → C
- T → A
- A → U
- G → C
- C → G
- C → G
- A → U

So the transcription of the entire DNA sequence ACG TAG CCA would be:

- ACG → UGC
- TAG → AUC
- CCA → GGU

Putting it all together, the resulting RNA strand is:

UGC AUC GGU

So, the answer is **UGC AUC GGU**.
