BIO ENG 150 Study Guide - Midterm Guide: Amphiphile, Ionic Strength, Nanometre
Document Summary
Fall semester, 2008: write down your name and the last digit of your sin in all the pages (2, define the following terms briefly: Unit of length equal to 1 x 10-9 m. In dna orgami, a staple strand is a single stranded dna sequence which hybridizes to sections of the scaffold dna to physically connect the two sections. Conformational change from typical b-dna (right handed) structure to z-dna (left handed) structure which occurs for certain sequence (high g-c pairs) when its solution"s ionic strength is increased. Amphiphilic amino acid containing molecule composed of a hydrophobic portion such as an alkyl chain and a hydrophilic peptide head self-assembles by formation of non- covalent bonds. Sin: ( : explain the difference between a natural holliday dna junction and a synthetic dna junction used to build dna nanostructures. Natural holliday junctions occur during homologous recombination and have sequence homology at branch points allowing for branch migration.
