The corresponding sequence in the RNA transcript is 5'-UACGACUG-3' . One of the differences between DNA and RNA is the fact that the RNA contains the base uracil instead of thyamine. The base pairing occurs between A and T, and G and C. DNA undergoes the process of transcription in the nucleus to generate RNA, which then undergoes translation (for mRNA) in the cytoplasm to yield proteins.
