DNA (2nd Half) Challenge There are 20 questions – 5 from each DNA topic covered As a group, quietly discuss each question and agree upon one correct answer. The group with the most correct answers will win.

#1 Mutations: 1 point Because agents such as UV radiation is known to cause DNA errors, it is an example of a _______.

Mutations: 2 points #2 Which type of mutations do not cause damage to proteins?

Mutations: 3 points #3 Name the type of cells that create the sperm and egg.
