Point mutations: Silent mutation, missense mutation, nonsense mutation - I explain all the forms to you in this video! As an example of missense mutation, we will look at sickle cell anemia. At the end you will also get a small example task on point mutations.

Missense mutation: Incorrect amino acid incorporated, thereby limiting the functionality of an enzyme. Nonsense mutation: A triplet that codes for an amino acid is converted into a stop signal, which stops the synthesis of a protein. --------------------------------------------- ➡ SUBSCRIBE FOR FREE (helps us a lot!): http://bit.ly/1FS9J00 ➡ ALL CHANNELS: The memory aid: http://bit.ly/1HuWiFb The thinking aid: http://bit.ly/1LEG0ub The technical aid: http://bit.ly/1HeqKA5 ➡ YOU CAN ALSO FIND US HERE!
