Transcription occurs in the nucleus of eukaryotic cells.
Here we’ll look at a single gene on one DNA sequence. In reality this could be thousands of base
pairs long, but I will be simplifying the size of all these products throughout this video.
RNA Polymerase binds to the promotor region of a gene - this area becomes available for binding
based on epigenetics. In other words, there are thousands of proteins (called transcription factors)
that either make it easier for RNA polymerase to bind, or those that inhibit its ability to bind this
promoter (often by a process called methylation). This will ultimately determine when and how
often this particular gene gets transcribed and is a vastly fascinating area of research right now.
