Document Summary
6. 1 specialized methods are used for genetic analysis of. Bacteria: relative genomic simplicity: fewer genes and fewer base pair, therefore less complex to study, haploid genomes: allow all mutation of be observed direction, without the interference from dominance interaction between alleles. Large number of progeny: enormous colony size, increase likelihood of event happening. Ease of propagation: microbes can be kept in liquid culture or cultured pates. Can be easy and inexpensive to maintain and require less laboratory space: numerous heritable differences: mutations are easily created, identified, isolated and manipulated for examination. Some bacteria can use lactose that breaks down into sugar glucose and galactose. Strains that are able to grow in lactose are designated lac+ otherwise are labelled as lac . Chapter 6: auxotroph/ auxotrophic strains bacteria that are unable to grow in minimal medium due to the lack of ability to produce an essential compound or has a more complex growth requirement.
