Description
BIOCH 200: Nucleotides and Nucleic Acids – “Secondary Structure of DNA” con’t | Protein Structure and Function – “What do Proteins do?” & “The Amino Acids” • RNA forms different structures than DNA o Adenine pairs with uracil o Usually single stranded structure o *Is stabilized by hydrogen bonds and base stacking interactions like DNA o *Has intrastrand base pairing (within the same strand) o *Many have complex secondary structures (combinations of ssRNA and dsRNA segments) o *Sometimes, guanine will pair with uracil as well! (GU)  *This type of base pair is known as a non-Watson Crick base pair. • Watson Crick Base Pairs: CG, AT, AU • *DNA forms interstrand base pairings (between differing strands) • *RNA “melting” consists of changing from a secondary RNA structure to a totally single-stranded product o *On the melting curve, the relative absorption at 260nm for RNA is higher than that of DNA since some single-strand segments already exist on the structure • *RNA forms a folded 3D structure sponta
