1. How do point mutations and frameshift mutations occur?*
O
They happen when ultraviolet light changes DNA's shape.
O
They happen when radiation changes the nucleotide bases.
O
They happen when there are errors in DNA replication.
O
They happen when there are errors in cell division.

In other cases, mutations alter the way a gene is read through either the insertion or the deletion of a single base. In these so-called frameshift mutations, entire proteins are altered as a result of the deletion or insertion. This occurs because nucleotides are read by ribosomes in groups of three, called codons.
