Definition and Types of Genetic Mutations
Genetic mutations are permanent changes in the DNA sequence of an organism. These changes can range from small alterations in a single nucleotide to large-scale rearrangements of entire chromosomes. Mutations can be either spontaneous or induced by environmental factors.
The following table provides a summary of different types of genetic mutations, their characteristics, and their effects:
Type of Mutation | Characteristics | Effects |
---|---|---|
Point mutations | Involve changes in a single nucleotide | Can result in changes in the amino acid sequence of a protein or the regulation of gene expression |
Insertions | Involve the addition of one or more nucleotides | Can disrupt the reading frame of a gene and result in non-functional proteins |
Deletions | Involve the removal of one or more nucleotides | Can also disrupt the reading frame of a gene and result in non-functional proteins |
Inversions | Involve the reversal of a segment of DNA | Can disrupt gene function if the inverted segment contains essential coding sequences |
Translocations | Involve the exchange of DNA between two chromosomes | Can result in the disruption of genes on both chromosomes |
