Document Summary
The flow of information where genetic info that is stored in our dna as a sequence of nucleotides gets transformed into phenotypic information in the form of proteins based off instructions. Represents how genetic information can get passed on as we replicate and reproduce. Proteins are composed of amino acids based on the genetic code. Dna can encode 20 different amino acids to make up proteins. Each codon specifies the addition of a specific a. a during translation. All have the same fundamental structure: alpha carbon, amino group -> connected to alpha c, carboxyl group -> connected to alpha c, r group side chain -> connected to alpha c. 20 different r groups (cid:0) therefore 20 different amino acids it is what distinguishes the different amino acids. Stereoisomers: d and l forms possible, but proteins only contain. There are 20 amino acids in 4 classes. Polar: side chains are hydrophilic -> like interacting with h20: 3 classes.
