BIO 1109 Study Guide - Phosphodiester Bond, Hydrogen Bond, Dna Replication
Document Summary
Chapter 10: nucleic acid structure and dna replication. Bacterial transformation experiments: pathogenicity: the ability to cause a disease. Nucleotides: three components: phosphate group, pentose sugar and nitrogenous base, compared with ribose sugar deoxyribose is missing a single oxygen atom, purine: adenine and guanine: double ring structure, pyrimidine: cytosine thymine and uracil: single ring structure. In a sugar ring the carbon atoms are numbered in the clockwise direction starting with the carbon atom to the right of the oxygen atom. Strand had directionality based on the orientation of the sugar molecules with the strand. Telomerase attaches dna sequences at the ends of chromosomes: telomeres of all of an organisms are composed of a series of the same repeated. Chapter 15: inheritance and phenotype determination: pangenesis: seeds that are produced by all parts of the body. Chapter 11: gene expression at the molecular level.
