that means you will see a kind of trail left behind... due to the fact that your eyes arent able to send more than a certain amount of info to your brain! Now im wondering how much that certain amount is... basically what is the refresh rate or response rate of the human eye!
In genetics, a promoter is a region of DNA that initiates transcription of a particular gene.ukaryotic promoter regulatory sequences typically bind proteins called transcription factors that are involved in the formation of the transcriptional complex. An example is the E-box (sequence CACGTG), which binds transcription factors in the basic helix-loop-helix (bHLH) family (e.g. BMAL1-Clock, cMyc).
The RNA primer provides this 3' end to allow nucleotides to be added. A promoter is a region on the DNA that allows RNA Polymerase (enzyme that builds the RNA molecule from the DNA template strand) to attach to the DNA. The RNA Polymerase makes the RNA strand that eventually becomes the mRNA used in protein synthesis. So, Primer used in DNA synthesis; Promoter used in RNA synthesis.
