• What is a mutation?

  The change in the sequence of the DNA base
• Why can the chance of mutation be increased?

  If the person is exposed to certain substances or types of radiation
• How can mutations affect a protein?

  The protein could change shape which could make it unable to perform its function
• What are the three different types of mutation?

  Insertions, deletions and substitutions
• What is insertion?

  A new base is inserted into the DNA base sequence, which can effect the way the bases are read
• What is deletion?
