I only watched the first one. The written subtitles were generally a
correct depiction of the events of DNA transcription, intron-exon
editing, and translation to protein. The video was completely
misleading making cellular proteins behave like complex spacecraft
smoothly coordinated are carefully organized. The process is actually
quite messy with all sorts of molecules careening around bumping into
things and the "correct" molecules bumping into the wrong place or the
wrong angle until it eventually gets it right. Only the "correct"
collisions, the ones with the right molecules at the right orientation
in the right location, stick. The others just bounce apart. But
there are such an incredibly number of molecular collisions that the
whole process works quite well.
I don't know just how much is possibly in modern molecular biology
labs but my impression is that pretty much every step can readily be
done in vitro. How the machinery works is no mystery and readily
obeys all the laws of biochemistry and physical chemistry.
