Match type of DNA mutation on the left with the definition on the right.
insertion
deletion
substitution
a base is removed
one base is switched for another
a base is added
Compare the mutated DNA sequence to the original. Identify the mutation as either an insertion, deletion, or substitution, and whether it is a frameshift or point, and whether it is a silent mutation.

According to the Base-Pair Rule...
A pairs with C and G pairs with T
Each nucleotide pairs with itself (ex A pairs with A)
A pairs with G and C pairs with T
A pairs with T and C pairs with G
Mutations are random.
True
False
All mutations are harmful to an organism or species.
