Sometimes as little as one base might be missing or it could be a few.On other occasions a couple of bases might be swapped around.It is also possible that during meiosis parts of chromosomes get damaged. If the genetic instructions are wrong what it does will also be wrong.ometimes as little as one base might be missing or it could be a few.

Small-scale mutations. 1  Point mutation â a change in one base in the DNA sequence. 2  Substitution â when one or more bases in the sequence is replaced by the same number of bases (for example, a cytosine substituted for an adenine). 3  Inversion â when a segment of a chromosome is reversed end to end. Copy number variation (CNV) is a type of mutation where large chunks of DNA are inserted, repeated or lost. 2  These regions of DNA can be between 10,000 and 5,000,000 bases long. 3  Duplication of genes.
