Genetics, 6e (Hartwell) Chapter 1 Genetics: The Study of Biological Information 1) How does DNA structure relate to its function? A) The three-dimensional structure allows DNA to catalyze chemical reactions. B) The order of nucleotides in a DNA strand specifies the order of amino acids in a protein. C) DNA folds in a variety of shapes, each with a unique function. D) The three-dimensional shape of DNA is critical for the storage of genetic information. Answer: B Section: 01.01 Topic: DNA: Life's Fundamental Information Molecule Learning Objective: 01.01.01 Relate the structure of DNA function. Bloom's: 2.
