deletion mutations

Deletion mutations occur when a piece of DNA is lost or removed from a chromosome or gene. This removal can vary in size, from a small segment of a few bases to larger sections containing many genes. Such mutations can disrupt how genes function, potentially leading to health issues or developmental changes. The effects depend on the size and location of the deletion; some may have minimal impact, while others can cause significant problems. Basically, a deletion mutation is like missing a part of a detailed instruction manual, which can alter the final outcome.
