In this section, I talk about changes to DNA Sequence, a.k.a Mutations. Mutations can lead to some significant problems, but in some cases, they can also lead to a trait that is beneficial to an organism, helping it better survive in its particular environment. There are different types of mutations, and these different types vary in how much of a difference they can make in an organism’s genetic code. Any change to the genetic code can result in a change in the proteins, which can result in a significant change in an organism’s traits.
Fortunately, there are some mechanisms in place to minimize spontaneous mutations, and I also talk about these things in this section.
