    Homologous Recombination Lecture Molecular Biology The ability for yeast and E. coli to do homologous recombination easily make it very easy to generate specific mutations. To “knock-out” a gene, you need to transform the cells with a PCR product containing an antibiotic resistance cassette flanked by the genomic DNA sequence where you would like to insert the cassette. Based on our lecture, diagram the process of recombination of the left flank of the following Kanamycin resistance cassette into the E....
