This puzzle contains names, terms and acronyms used to describe the physical causes and genetic results of mutation. Find these thirty one terms and correctly transfer them to the blanks organized below. Then use the remaining letters to complete the sentence describing the importance of this process. Your success will be rewarded. Good hunting! You can also send me comments or suggestions, or return to my home page.
DNA changes can be either S _ _ _ _ _ _ _ _ _ _ or I _ _ _
_ _ _ in the lab. For example, a, b and _ rays from R _ _ _ _
_ _ _ _ _ _ I _ _ _ _ _ _ _ are C _ _ _ _ _ _ _ _ _ _ _ . T _
_ _ _ _ _ D _ _ _ _ _ result from _ _ R _ _ _ _ _ _ _ _. A single
B _ _ _ T _ _ _ _ _ _ _ _ _ or T _ _ _ _ _ _ _ _ _ _ _ can be
caused by a natural T _ _ _ _ _ _ _, _ _ S alkylation or a base
analogue like B _ _ _ . They produce S _ _ _ _ _ , M _ _ _ _ _
_ _ or N _ _ _ _ _ _ _ phenotypes when expressed. A _ _ _ _ _
_ _
D _ _ _ make cells add extra bases into their _ _ _ . I _ _ _
_ _ _ _ _ or D _ _ _ _ _ _ _ of a base causes a F _ _ _ _S _ _
_ _ . Reversing part of a sequence is an I _ _ _ _ _ _ _ _ . Some
MUTATIONs are C _ _ _ _ _ _ _ _ _ _ _ _ L _ _ _ _ _ since they
kill only in certain environments. Major damage, for example by
_ -rays, induces _ _ _ repair which ironically is mutagenic.
