The Molecular Basis of Inheritance Life?s Operating Instructions * In 1953, James Watson and Francis Crick introduced an elegant double-helical model for the structure of deoxyribonucleic acid, or DNA * Hereditary information is encoded in DNA and reproduced in all cells of the body * This DNA program directs the development of biochemical, anatomical, physiological, and (to some extent) behavioral traits * DNA is copied during DNA replication, and cells can repair their DNA Concept 16.1: DNA is the genetic material * Early in the 20th century, the identification of the molecules of inheritance loomed as a major challenge to biologists The Search for the Genetic Material: Scientific Inquiry

Nucleic Acids, DNA Structure, and Chromosomes Nucleotides are the building blocks of nucleic acids One (NMP), two (NDP), three (NTP) phosphates 5 different bases: A, G, C (DNA and RNA), T (DNA), U (RNA) 2 different sugars: ribose (RNA), deoxyribose (DNA) Two kinds of 5-carbon sugars Five kinds of nitrogen containing bases The sugars and bases are linked through a glycosidic bond nucleoside = N-containing base linked to a 5 carbon sugar (no phosphate) nucleotide = N-containing base linked to a 5 carbon sugar & one or more phosphates Nucleotides are linked through phosphodiester bonds Link between nucleotides: 5? C of sugar - phosphate- 3? C of sugar (backbone) Variable portion: base

Chapter 16 The Molecular Basis of Inheritance Lecture Outline Overview: Life?s Operating Instructions In April 1953, James Watson and Francis Crick shook the scientific world with an elegant double-helical model for the structure of deoxyribonucleic acid, or DNA. Your genetic endowment is the DNA you inherited from your parents. Nucleic acids are unique in their ability to direct their own replication. The resemblance of offspring to their parents depends on the precise replication of DNA and its transmission from one generation to the next. It is this DNA program that directs the development of your biochemical, anatomical, physiological, and (to some extent) behavioral traits. Concept 16.1 DNA is the genetic material The search for genetic material led to DNA.
