Three ways mutations can occur in genes are: 1. Insertion: Extra DNA nucleoties are added to the DNA strand. 2. Deletion: DNA nucleotides are deleted, therefore, changing the â¦ DNA sequence. 3. Translocation: parts of chromosomes are exchanged.or example, this can happen during crossover during the formation of gametes. Substitution mutations happen when one nucleotide (the smallest unit of DNA) is replaced by another. These are caused by a number of chemicals that look like something in between both of those nucleotides.
