BIOL 102 Lecture Notes - Lecture 5: Red Blood Cell, Deoxyribonucleotide, Uracil
Document Summary
Different functional domains in a protein; individual components that can be chopped off and still be the same in a solution. All protein structures rely on the primary structure; sickle-cell disease: one amino acid change = glu to val; structure changed secondary, tertiary, quaternary structure, causing the odd shape of the red blood cell. Not all changes in the primary structure completely affect the quaternary structure of proteins. Responsible for storage, expression and transmission of genetic information. Dna: genetic info for coding (like blueprint) Rna: takes info and sends it to different parts of the cell. Pyrimidines (single ring): c&t (way to remember: you cut a pie) Mutation c to u will not make a difference; one out of 1000 or so. Cytosine sometimes changes to uracil in dna (mutation); a reader comes and changes it to cytosine because it recognizes that it is not suppose to be in dna. Thymine helps with double-helix shape better than uracil.
