What genetic event does the DSB homologous recombination model account for that the Holiday model does not?

Read the statements below and determine which f the recombination mechanisms that it matches with - there could be more than one match or there could be no match at all. For each box, place a YES or NO in the box. Statement 1. Donor cell produces a pilus in order to exchange DNA with recipient cell. 2. Mediated by a bacteriophage. 3. Always involves a plasmid. 4. Allows recombination of chromosomal DNA fragments from donor to recipient. 5. Requires rolling circle replication. 6. Requires donor to recipient cell direct contact. 7. Allows the uptake of free DNA fragments from the environment. 8. Is always horizontal gene exchange. 9. Allows movement of genes from a plasmid to a chromosome. 10. Requires a donor cell to infect a recipient cell in order for recombination to occur. 11. Involves plasmid integration into the chromosome prior to recombination. 12. Involves incorrect packaging of donor DNA into a phage particle in order for recombination to occur. 13. Involves DNA that was…

based on the image answer the following question 1. what is the gene order 2. what are the map distances in recombination percentages.

what are recombination nodules?

3. An F* strain, marked at 10 loci, gives rise spontaneously to Hfr progeny whenever the F factor becomes incorporated into the chromosome of the F* strain. The F factor can integrate into the circular chromosome at many points, so that the resulting Hfr strains transfer the genetic markers in different orders. For any Hfr strain, the order of markers entering a recipient cell can be determined by interrupted mating experiments. From the following data for several Hfr strains derived from the same F* strain, determine the order of markers in the F* strain. ww wwww Hfr Strain Markers Donated in Order 1 -Z-H-E-R> – 0-K-S-R –> – K-O-W-I > – Z-T-I-W > 4 – H-Z-T-I>
