In DNA transcription, the sequence of nucleotides in the DNA is used to synthesize a complementary RNA sequence. The base pairing rules for RNA 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.
Given the DNA sequence TAGC, the corresponding RNA sequence would be:
- T → A
- A → U
- G → C
- C → G
Therefore, the transcription of the DNA sequence TAGC to RNA is **AUCG**.
