which enzyme process DNA breaks to generate single stands for invasion in homologous recombination
Answers
Answer:
Homologous recombination, the exchange of genetic material between two strands of DNA that contain long stretches of similar base sequences. Homologous recombination occurs naturally in eukaryotic organisms, bacteria, and certain viruses and is a powerful tool in genetic engineering.The genome of a cell is continuously damaged, which is inevitable because DNA damage often arises as a result of normal cellular processes. ... The result is double-strand breaks (DSBs) in the chromosome. A DSB can also be caused by environmental exposure to irradiation, other chemical agents, or ultraviolet light (UV).In eukaryotes. Homologous recombination (HR) is essential to cell division in eukaryotes like plants, animals, fungi and protists. In cells that divide through mitosis, homologous recombination repairs double-strand breaks in DNA caused by ionizing radiation or DNA-damaging chemicals
