A promoter and a start codon are similar in the way that both are sequences of nucleic acids that are required to start important processes, and both determine the sites where the processes will begin. The key difference is that the promoter is needed to start transcription and the start codon is needed to start translation. Also, the promoter is a DNA sequence only, and the start codon is a sequence found within the mRNA.
