The impact of cessation of smoking on the frequency of formation of adducts. Introduction: Smoking is dangerous to health because it can lead to the formation of covalent bonds within our body. These covalent bonds result in the formation of adducts. Ultimately, smoking results in the formation of oral cancer.

Question

Any permanent change to the structure of DNA is considered a mutation. A somatic cell mutation affects only the individual organism, while a germline mutation is passed onto the next generation. For example, excessive amount of exposure to UV rays can lead to skin cancer. Although this type of mutation occurs in the somatic cells, every individual has different susceptibility to skin cell mutations upon exposure to UV rays. The susceptibility is located in the germ cell and is heritable. The individuals who choose to overexpose themselves to UV rays increase their likelihood of obtaining undesirable mutations in their somatic cells. Unlike suntanning, there are other activities we engage in that can lead to germline mutations. These activities should be avoided if possible as they lead to heritable mutations and cancer. Using 200 words or less, identify one human activity that can lead to a heritable mutation. Explain how it affects the individual and how it can be passed onto the…
