Explain Point Mutations gene?

Mutations involving single genes occur by addition, substitution, or deletion of a single base in DNA. Such mutations, called point mutations, can cause a protein to be nonfunctional or to form a chain-terminator codon that stops translation. Insertions or deletions, called frame-shift mutations, shift reading of the code by one or more bases so that all amino acids produced after the addition or deletion are affected.
