Very well explained. I just have 2 questions. 1) How does the RNA polymerase know where to start and stop transcribing and 2) If there are 2 start codons before the next stop in the mRNA does that mean you get overlapping protein sites?
In eukaryotic cells, transcription is normally thought to originate at a TATA box. Basically a sequence that the polymerase or proteins that attract the polymerase can bind to. I believe there is then a termination sequence also. As for translation, in eukaryotic cells, it looks for a Kozak sequence to initiate translation.
You didn't mention any Kozak sequence in your video, though from what I found, it contains the start codon. So is it possible to get 2 TATA boxes or Kozak sequences before the next termination sequence or stop codon? Would that be overlapping genes / protein templates?
The goal of the video is to basic, therefore I did not mention TATA boxes and Kozak sequences. Theoretically, two kozac sequences could be present, however, I don't know if that is actually the case. It is more likely that alternative splicing would be used to obtain different protein products.
Thanks for making this!

Even though I am in advanced molecular biology now, I tend to always forget the basics! Great review!!

@PureDomination48 I have a video on DNA nomenclature that should help clrify that question.
