What are the methods of mutant isolation?

Mutant isolation methods include chemical mutagenesis, where chemicals induce mutations in the DNA; physical mutagenesis, which employs radiation (like X-rays or UV light) to cause genetic changes; and biological mutagenesis, utilizing viruses or transposable elements to introduce mutations. Additionally, genetic screening techniques, such as forward and reverse genetics, help identify and isolate mutants with desired traits. Lastly, advanced methods like CRISPR/Cas9 allow for precise gene editing and isolation of specific mutations.
