&gt;something called transcription, which involves 200,000 rRNA (ribosomal DNA) molecules. Then this rDNA is involved in making 10 million proteins through 10,000 different pathways.<p>I&#x27;m curious how this elementary error crept in here (he means mRNA, not rRNA, and rDNA is not a thing). Poor editing? A gap in the education of the good doctor?
