DNA synthesis starts at the Replication Origin. In what way(s) do you think that the Replication Origin might be similar to a Promoter and in what ways might it be different?
They are conserved sequences, and they both bind proteins to initiate the synthesis of a strand. However, the strands that they initiate synthesis of are different, as well as the proteins that they bind. DNA polymerase binds at the Replication Origin and initiates the copying of DNA. Whereas RNA polymerase binds to the promoter and initiates the transcription of RNA for protein synthesis.
