Mutations are the changes in the DNA sequence. Or in other words, changes in parts of genes in chromosomes. The base sequences are messed up! 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.

Point Mutations. A point mutation is a single-letter swap -- an exchange of two bases (adenine to cytosine, for example) at a single location in the DNA molecule. Since the sequence of letters in a gene determines the sequence of amino acids in the protein it encodes, a point mutation can change the amino acid sequence of the resulting protein. Sometimes a change in the protein's amino acid sequence can have dramatic results. For example, sickle cell disease occurs when a single-point mutation in the gene that encodes the hemoglobin molecule results in deformed red blood cells.
