mechanisms; 2.2.1 Method 1: Ionizing radiation (usually X-rays and gamma-rays); 2.2.2 Method 2: Chemical mutagens; 2.2.3 Method 3: Transposons as mutagens; 2.2.4 Method 4: Targeted gene disruption (a variant on transposon mutagenesis); Box 2.4 Making phenocopies by RNAi and co-suppression; 2.3 What phenotype should you screen (or select) for?; 2.4 Actually getting started |
2.4.1 Your starting material2.4.2 Pilot screens; 2.4.3 Keeping too many, keeping too few; 2.4.4 How many mutants is enough?; Summary; Box 2.5 Reviews of mutant isolation schemes and techniques in various organisms; 3: The complementation test; 3.1 The essence of the complementation test; Box 3.1 A more rigorous definition of the complementation test; Box 3.2 An example of using the complementation test in yeast; 3.2 Rules for using the complementation test; Box 3.3 Transformation rescue is a variant of the complementation test |
Box 3.4 One method for determining whether or not a dominant mutation is an allele of a given gene, or how to make dominants into recessives by pseudo-reversion3.3 How might the complementation test lie to you?; 3.4 Second-site non-complementation (SSNC) (non-allelic non-complementation); 3.4.1 Type I SSNC (poisonous interactions): the interaction is allele-specific at both loci; Box 3.5 Pairing-dependent complementation: transvection; Box 3.6 Synthetic lethality and genetic buffering; 3.4.2 Type 2 SSNC (sequestration): the interaction is allele-specific at one locus |
3.4.3 Type 3 SSNC (combined haplo-insufficiency): the interaction is allele-independent at both loci |

Sommario/riassunto |
|
Advanced Genetic Analysis brings a state-of-the-art, exciting new approach to genetic analysis. Focusing on the underlying principles of modern genetic analysis, this book provides the 'how' and 'why' of the essential analytical tools needed. The author's vibrant, accessible style provides an easy guide to difficult genetic concepts, from mutation and gene function to gene mapping and chromosome segregation. Throughout, a balanced range of model organisms and timely examples are used to illustrate the theoretical basics. Basic principles - Focuses students attention on t |
