Chapter 20 DNA Technology and Genomics Overview: Understanding and Manipulating Genomes One of the great achievements of modern science has been the sequencing of the human genome, which was largely completed by 2003. Progress began with the development of techniques for making recombinant DNA, in which genes from two different sources?and often different species?are combined in vitro into the same molecule. The methods for making recombinant DNA are central to genetic engineering, the direct manipulation of genes for practical purposes. Applications include the introduction of a desired gene into the DNA of a host that will produce the desired protein.

Chapter 13 Meiosis and Sexual Life Cycles Overview: Hereditary Similarity and Variation Living organisms are distinguished by their ability to reproduce their own kind Heredity is the transmission of traits from one generation to the next Variation shows that offspring differ in appearance from parents and siblings Genetics is the scientific study of heredity and variation Concept 13.1: Offspring acquire genes from parents by inheriting chromosomes In a literal sense, children do not inherit particular physical traits from their parents It is genes that are actually inherited Inheritance of Genes Genes are the units of heredity Genes are segments of DNA Each gene has a specific locus on a certain chromosome One set of chromosomes is inherited from each parent

Eugenics ? Traits Studied Charles Davenport was the director of three institutions based at Cold Spring Harbor ? the ERO, the Biological Laboratory, and the Carnegie Institute of Washington?s Station for Experimental Evolution He noted in his 1909 Annual Report that the inability to conduct controlled experiments ruled out human genetics as a suitable topic for the Station for Experimental Evolution He and his wife published 4 papers between 1907 and 1910 that applied Mendelian principles to the human inheritance of eye color, hair color, hair texture and pigmentation The paper on skin pigmentation made the first reference to polygenic inheritance ? a trait influenced by two or more genes The eye color paper relied on data supplied by ?school principals and other friends?

Chapter 17 From Gene to Protein Lecture Outline Overview: The Flow of Genetic Information The information content of DNA is in the form of specific sequences of nucleotides along the DNA strands. The DNA inherited by an organism leads to specific traits by dictating the synthesis of proteins. Gene expression, the process by which DNA directs protein synthesis, includes two stages called transcription and translation. Proteins are the links between genotype and phenotype. For example, Mendel?s dwarf pea plants lack a functioning copy of the gene that specifies the synthesis of a key protein, gibberellin. Gibberellins stimulate the normal elongation of stems. Concept 17.1 Genes specify proteins via transcription and translation

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.
