Hey guys - I'm back with another blog post. Today we will be talking about genetic mutation. A genetic mutation is a change in the cells DNA which can have good or negative effects. For example, Godzilla was a genetically mutated lizard. That is a example of a positive mutation.
A gene is a unit of heredity. Genes are important because they give you all your feature like eye color or body shape. When your genes get messed up the changes can be good or bad (most of the time bad). Genetic mutation happens mostly when your cells split. It is extremely hard to live if you have a bad genetic mutation. Some will effect how fast you age and others might effect what your body looks like. You can even have two heads or two bodies! Just because this stuff can happen to your DNA, doesn't mean your cell will let it stay there. In your cells you have DNA repair and it will get rid of the mess up in the DNA as soon as it can. If the DNA repair can find the problem it can become permanent.
Even though many bad thing can happen to you in genetic mutation, some good things can happen to you too. For example, say you are a bird and you get an extra long beak. You would be able to get food more effectively than if you had a small one you would have had without the mutation. If you get the long beak, you would have a better chance of passing it down to your kids.
Here are some examples of things that cause mutations: DNA doesn't copy the accurately, external influences such as exposure to a chemical such as tobacco, deletion occurs in other words a section of the DNA is deleted or insertion meaning extra code is added to the DNA.
Well, that's all for now. Bye.
