The template strand of the DNA is copied during transcription, and its sequence is the complement of the RNA transcript. The coding strand of the DNA has the same sequence as the RNA transcript (except for T in the DNA and U in the RNA). Hence, for example, the start codon for transcription is 5'-ATG in the coding strand of the DNA and 5'-AUG in the mRNA. By convention, gene, promoter, and regulatory sequences in DNA are written as they appear in the coding strand.
