Answer #1

During the meiosis process of eukaryotic cells chromosomal crossing over is taken placed and the product generated from meiosis is called as a recombinant. In the crossing over homologous chromosomes can pairs with each other and transfer the genetic information from each other. In independent assortment a novel set of genetic information that can be passed on from the parents to the offspring. So the output cell of meiosis has the same genetic constitution of one of the input cells in the recombination.

If the DNA repairs via homologous recombination then both the damaged part is replaced by original one so the length is not reduced and it revert back to its original form.? The recombination mechanisms performed by Rec A,RecB RecC proteins. So this recombination process can used to repair DNA damage.

2. Haploid yeast cells that preferentially repair double-strand breaks by homologous recombination are especially sensitive to agents that cause double-strand breaks in DNA. If the breaks occur in the G1 phase of the cell cycle (before DNA replication), most yeast cells die; however, if the breaks occur in the G2 phase (after DNA replication), a much higher fraction of cells survive.

Pick the statement about DNA repair that is true. Base excision repair removes bulky DNA lesions like thymidine dimers. Nucleotide excision repair is used immediately after replication to correct errors that escape proofreading. Direct repair directly changes modified bases back to their original structure. Mismatch repair reduces the fidelity of DNA polymerase. SOS repair uses DNA glycosylases to recognize and remove a specific type of modified base.

In theory, a genome editing method like CRISPR could be paired with repair by homologous recombination to cure DMD. However, repair by homologous recombination is rather inefficient. An alternative method is to use genome editing, paired with non-homologous end joining (NHEJ). Briefly explain how this strategy would work for DMD, and if it were 100% efficient, what you would expect it to do patient symptoms.
