While blizzards often feature extreme cold and heavy snow, there are actually no temperature or snow depth requirements for a storm to qualify as a blizzard. Occasionally, blizzard conditions will present when there is no precipitation.
Definition. A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.efinition.

Likewise, the protein made from the ârecipeâ of a mutated gene will not be the correct protein. Many small gene mutations do not cause major problems. But other mutations can have very serious health consequences because of how they affect protein synthesis. An example of a mutation is the sickle cell gene.This abnormally shaped gene may have mutated for a good reason because one sickle cell gene protects its carrier from the deadly parasitic disease malaria.ikewise, the protein made from the ârecipeâ of a mutated gene will not be the correct protein.
