The video is really interesting and good that I wanted to use it in some of my English class. Maybe my students can use it for their presentations. Also there is background music which may explain the relevant biology. I do not know nucleic acids, enzymes, ribosome, kinesins and a few chains. I just read it (Biology) when I was a student at Ankara Anatolian High School, in Ankara city. I’ve forgotten most of them so let me ask my wife :)) I suppose that she’ll talk about it more than me.
If you are interested in Biology, pls click it and I think you have too wait for a few minutes or seconds. Sometimes it takes time. Have a good time.
