This video tutorial by Nicolas covers the concept of codons in genetics, explaining how they are sequences of three nucleotides on mRNA that specify amino acids. The tutorial details the four types of RNA bases and how they combine to form 64 possible codons. It further explains that out of these, 61 codons specify amino acids, while 3 are stop codons. The video concludes with a summary of these key points and encourages viewers to engage with future content.
