NGSS.HS-LS4-2

Mutations that change a single base pair, usually involving a substitution of one base for another:

• chromosomal mutation

• polyploidy

• translocation

• point mutation

If a point mutation does not change the order of the amino acid sequence, this is called a:

• nonsense mutation

• silent mutation

• missense mutation

• frameshift mutation

Insertions and deletions are also known as:

• frameshift mutations

• chromosomal mutations

• silent mutations

• polyploidy

If a mutation codes for "stop" in the amino acid chain, this is called a:

• nonsense mutation

• missense mutation

• silent mutation

• frameshift mutation
