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....

The process of homologous recombination is a means to repair double-strand breaks, the most lethal form of DNA damage. Arrange the sequence of events in the proper order: 1. ATR recognizes single-stranded ends, binds to them, and initiates signaling. 2. RAD51 complexes with ssDNA and searches for homologous sequences. 3. MRN nuclease trims the 5' ends, leaving ss-3' ends that are coated with replication protein A. 4. ATM activates a nuclease in MRN and signals downstream effectors. 5. RAD51-ssDNA complex...

6.) During meiosis, when crossing-over occurs between two homologous chromosomes, it does not happen at a single point, but rather two points with a stretch of DNA in between. a. What are the two junction points called? b. What is the region between the two points called and what is different about this region compared to how double-stranded DNA usually is? c. If the region described in b.) is located within a gene and the two homologues have different alleles...
