There are different ways that a mutation in the DNA base sequence can occur: Remember that every group of three bases in a DNA sequence codes for an amino acid, This means that insertion mutations cause what is known as a, Like an insertion mutation, a deletion mutation, Substitution mutations can take three forms, Note that a stop codon provides a signal for the cell to stop translation of the mRNA molecule into an amino acid sequence, Duplication is a type of mutation that involves the, A whole gene or section of a gene is duplicated so that, Overtime, the second copy can undergo mutations which enable it to develop new functions, Gene and chromosome duplications occur in all organisms, though they are, Inversion mutations usually occur during crossing-over in meiosis, The result is a large section of the gene that is 'backwards' and therefore multiple amino acids are affected, Inversion mutations frequently result in a non-functional protein, In some cases an entirely different protein is produced, The mutation is often harmful because the original gene can no longer be expressed from that chromosome, If the other chromosome in the pair carries a working gene the effect of the mutation may be lessened, The polypeptide can affect the phenotype, e.g. ; Bach, H.
