Document Summary
Many exposures to radiation is a cause of just living on this planet. Ionizing radiation creates ros that damages dna: decay of radioactive iodine and cesium creates ionizing radiation, cause reactive oxygen molecules, by removing electrons. The chromosomes get broken from the ionizing radiation. Deletion, and part of the chromosomes can be removed; they are mutagenic changes. Addition, which is where an extra part of the chromosome is added. C. ) inversion: when parts of the chromosome are moved, as the placement of particular genes is imperative to life. D. ) translocation: gets moved from the genome to any other chromosome. Genes need to be in the proper place. Unequal recombination can generate copy number variations (cnv) When a gene has an extra number of the same gene is a huge bonus to the population, as it allows for the population to evolve; they evolve this specific gene.
