2). The basic premise of transposon-based mutagenesis is that the insertion of a transposon into a given gene will disrupt the function of that gene.

Or sterile that prevents balancer homozygotes from surviving. ] Inversions suppress crossingover lor a variety of reasons. Small paracentric inversions (those that do not include the centromere) actually suppress the occurrence of recombination, especially in the regiom surrounding their breakpoints (Novitski &. Braver 1954; Theurkauf &. Hawley 1992). lMger paracentric inversions suppress crossingover by preventing the recovery of aossover chromatids (Sturtevant &; Beadle 1936). 1, the crossover event within the inversion cre· Exchange First division , ates a dicentric bridge and an acentric fragment, both of which are excluded from the meiotic product that is made availdble to the sperm for fertil· ization.

3 Reason 3: To obtain mutation toolsfor structure-function analysis There will come a point in your analysis when you know the sequence of the gene and its protein product. Perhaps the structure ofthat protein provides dues to its function. The next step is a high-resolution structure-function study of this protein to determine what functions are carried out by which amino acid domains. A large collection of missense mutations (mutations that result in the replacement of a single amino acid) now becomes an invaJuable tool in your analysis, precisely because it allows you to examine the effects of changing the protein sequence "one amino acid at a time.
