Medical Genetics Gene Mutation Change in genes caused by change in structure of the dna
Medical Genetics Gene Mutation Change in genes caused by change in structure of the DNA
Medical Genetics 1. Base(s) in DNA is (are) changed to other(s), or a base(s) is (are) added or removed 2. Rearrangements of the chromosomes occur and are also considered

Medical Genetics Mutations can occur at a spontaneous rate, or a far greater rate when there is exposure to mutagenic agents

Medical Genetics Exposure to too high a level of mutagens can threaten the survival of a species, e. g frog species in the states of Washington and Oregon are facing extinction. This appears to be caused by reduced atmospheric ozone, and the resulting increased level of ultraviolet radiation

Medical Genetics Ultraviolet (UV) light UV light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects like bumblebees can see them!

Medical Genetics Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet the far ultraviolet and the extreme ltraviolet
