Where do mutations occur DNA?

Mutations in DNA can occur at various locations within the genome, including coding regions (exons), non-coding regions (introns), regulatory sequences, and intergenic regions. They can arise during DNA replication, repair processes, or due to environmental factors such as radiation and chemicals. Mutations can involve changes in single nucleotides (point mutations), insertions, deletions, or larger structural changes. The specific location and type of mutation can significantly impact gene function and, consequently, an organism's phenotype.
