Mutations Review

A mutation that changes a single nucleotide, but does not change the amino acid created

• neutral mutation

• nonsense mutation

• point mutation

• silent mutation

a mutation in which one or more nucleotides are added to a gene

• point mutation

• deletion mutation

• inversion mutation

• insertion mutation

mutation that shifts the "reading" frame of the genetic message by inserting or deleting a nucleotide

• inversion mutation

• insertion mutation

• frameshift mutation

• nonsense mutation

Any of the pairs formed between complimentary bases in the two nucleotide chains of DNA, such as A-T and C-G (DNA); A-U and C-G (RNA).

• nonsense mutation

• base pairs

• anticodon

• silent mutation

single-stranded nucleic acid that contains the sugar ribose

• RNA

When a portion of the DNA is shifted in one direction due to a deletion or insertion?

• frameshift

• gene

• deletion

• substitution

What mutation has occurred here? 
old - T-G-A-C-C-A
new - T-G-A-G-C-A

• Substitution
