- What is a genetic mutation?Answered by verified global health professionalsA genetic mutation is a permanent alteration in the DNA sequence that makes up a gene. These changes can occur naturally during DNA replication or be induced by environmental factors such as radiation or chemicals. Mutations can vary in type and effect; some may involve a single nucleotide change, known as a point mutation, while others might involve larger-scale alterations like insertions, deletions, or duplications of DNA segments. Depending on their nature and location, genetic mutations can have a range of effects on an organism, from benign variations to serious genetic disorders. In some cases, mutations can be inherited from one or both parents, potentially leading to hereditary conditions, or they may arise spontaneously in an individual’s cells.Read moreDr. Mayank Saxena2 years exp · India · MBBSSee more results
