G, C, A, U, U, G

C, G, A, U, U, C

Answer 1

To transcribe the DNA sequence GCATTG into mRNA, we need to replace each DNA nucleotide with its corresponding RNA nucleotide:

- G (guanine) pairs with C (cytosine)
- C (cytosine) pairs with G (guanine)
- A (adenine) pairs with U (uracil)
- T (thymine) pairs with A (adenine)

So, the transcription of the DNA sequence GCATTG would proceed as follows:

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

This gives us the mRNA sequence: **CGAUUC**.

Therefore, the correct response is:
**C, G, A, U, U, C**.
