Genetic Mutation-How are we all not mutated?!?
I was amazed by this article because it illustrated the commonly overlooked fact that if one thing goes wrong with our cells the manifestation can have a devastating impact on our lives and functioning. Even though the haploid human genome contains three billion nucleotides just one single pair mutation can have significant physiological effects on the human body. (One example was sickle cell anemia). Mutations are significantly different from polymorphism because mutations almost always imply something "wrong" with the body while polymorphism occurrences are normal variations.
Even more astonishing is the fact that DNA can change for a number of different reasons and only one change shows physically. That was the main thing about this article that amazed me. It seems like more people should have genetic mutations because of how simple it is for the body to make one and how complex it is for the body to get everything perfectly right.
I would suggest this article to anyone who would like to discover the complexity of the body or renew their knowledge of mutations. It is a good source.
