RE: The Building Blocks of Life - Basics

Nice write up on amino acids and proteins. Some typos: "pears" should be "peers" and "glycine" with an e in english. Some of you with biology background may be wondering why 21 amino acids, and learned about 20 amino acids. This is because the genetic code encodes 20 amino acids and in humans we also use a special amino acid called selenocysteine but it is not directly coded in our genetic code but uses the UGA codon (and other sequences within mRNA), which would normally be a stop codon.

Always those typos. Damn it.
