Oxygen free radicals are very commonly known as Reactive Oxygen Species(ROS). These ROS possesses a unpaired electron. Due to their unpaired electron they are very very reactive, and also they react with cellular DNA to form adducts or directy induced mutation by chemical changes.
By chemical changes or by forming adducts they mostly causes nonsense physical mutation, because oxygen free radicals causes chemical changes in the DNA bases so they mispaires. For examples - oxydation of Guanine(G) forms 8-oxy-7,8-dihydrodeoxyguanine which mispaires with Adenine(A) so results in a nonsence mutation that change the protein structure.

Which mutation is most likely to have a severe impact on the phenotype of an organism if it occurs within the first several bases of a gene coding region? A) a frameshift mutation of three nucleotides B) a missense mutation affecting one nucleotide C) a missense mutation affecting three nucleotides D) a silent mutation affecting one nucleotide E) a frameshift mutation of one nucleotide

In cross-fertilization insects are used to pollinate the plants, whereas in self- fertilization the investigator pollinates the plants. In self-fertilization the pollen from one plant is used to fertilize the egg from another plant. In cross-fertilization the pollen from one plant is used to fertilize the egg of another plant. In cross-fertilization...

Explain what classifies a mutation as “temperature‑sensitive” by comparing phenotype(s) with a wildtype allele. How is this type of phenotype explained by protein behaviour? Would the following types of mutations most likely have: severe effects, mild effects, or no effect on protein function? Briefly explain your answers. Note that there may be more than one correct answer, but you need only to give one sensible answer and explain your reasoning. [6 marks] A nonsense mutation occurring in sequences encoding amino...
