A blog covering and explaining the Edexcel IGCSE Biology specification for the 2016 summer exams. If you are doing just double science, you do not need to learn the stuff for paper two, if you are doing triple you will need to learn all (GOOD LUCK!) I have separated the papers to make files easier to find. Hope it helps :)

3.29 understand that a mutation is a rare, randon change in genetic material that can be inherited
A mutation is a rare, random change in an organism's DNA (basically, a mutation in a gene). This can be inherited. Mutations are often harmful as they change the sequence of the DNA bases. This could stop the production of a certain protein, or produce the wrong protein.
