Enhancers stimulate or increase the rate of transcription. Promoters are typically adjacent to the transcriptional start site and are highly position dependent, whereas enhancers function at a distance from the gene and function independently of position and direction. 3) The TATA binding protein (TBP) binds most eukaryotic promoters at the TATA box and positions the active site of RNA polymerase over the transcriptional start site. 4) Transcription and replication are similar in that both use a DNA template, synthesize molecules in the 5’ to 3’ direction, synthesize strands that are antiparallel and complementary to the template, use NTPs as substrates and use enzymes and other protein complexes for the process.
