#BioDub RNA Transcription Video

1/12/2017

 
This video shows RNA transcription in much more detail. Some of the things you should notice is that the entire sequence of DNA is not transcribed, only one small part. That small part is one gene. The blue-ish molecule that races along the DNA is RNA polymerase. As it races along the DNA you can see it briefly separating the 2 DNA stands and then leaves behind a single stranded RNA molecule; you can even see the RNA nucleotides being drawn into the process. At the end of the gene (at the end of  transcription) the RNA is released to eventually make its way out of the nucleus.
