Mendelian genetics. Video transcript. Voiceover: So, today we're going to talk about the different types of genetic mutations that you would find in a cell. But first, I want to review the central dogma of molecular biology and how the genetic information of a cell is stored in the form of DNA, which is then transcribed to form RNA. Exercise 8 - En mutation practise (Lesson 14 and recaps of Lessons 8 & 9) Although in practice you generally won't find yourself using this nearly as often as soft mutation or nasal mutation, it is still used enough for you to need to know it!

The mutation leads to genetic variations among species. Positive mutations are transferred to successive generations.

DNA base mutations may not affect a gene's protein, or they may have a serious effect. It depends on the mutation and the function of the protein coded by the gene. There are other types of mutations to consider. Watch the following video to find out more about mutations.
