mutagenezy

Mutagenezy refers to the process by which mutations are introduced into the genome of an organism, typically through deliberate human intervention. Mutations are permanent changes in the DNA sequence that can alter gene function, leading to variations in traits such as disease resistance, growth rate, or biochemical properties. This technique is widely used in genetic engineering, biotechnology, and research to study gene function, develop genetically modified organisms (GMOs), and improve crop yields or livestock productivity.

The term "mutagenezy" is not as commonly used as "mutation induction" or "genetic modification," but it encompasses methods like chemical mutagenesis, radiation treatment, and more recently, CRISPR-Cas9 gene editing. Chemical mutagens, such as ethyl methanesulfonate (EMS) or ethylnitrosourea (ENU), introduce random changes in DNA by altering bases or causing deletions. Radiation, including X-rays or gamma rays, can break DNA strands, leading to mutations during repair processes. These methods are often used in traditional breeding programs to generate genetic diversity.

More precise approaches, such as CRISPR-Cas9, allow targeted mutations at specific DNA sequences. This technology has revolutionized genetic research by enabling efficient and accurate edits with minimal off-target effects. Mutagenezy is also applied in medical research to create animal models of human diseases, aiding in the development of therapies and drug testing.

While beneficial for scientific and agricultural purposes, mutagenezy raises ethical and environmental concerns. Unintended mutations or unintended spread of GMOs could have ecological consequences, and public perception often remains divided over the safety and morality of genetically modified organisms. Regulatory frameworks exist in many countries to oversee the use of mutagenezy in agriculture and biotechnology, ensuring safety and transparency.
