Dna Mutations
DNA mutations are changes in the sequence of nucleotides within an organism's DNA. These alterations can occur spontaneously or be induced by external factors such as radiation, chemicals, or errors in DNA replication. Mutations can range from single nucleotide changes to large-scale rearrangements of genetic material, resulting in genetic diversity within populations. Mutations can have varying effects on an organism, from being neutral to causing genetic disorders or contributing to the evolution of species.
