In F2 screens, a mutagen, such as ethylnitrosourea (ENU), is used to generate hundreds of point mutations in the male pre-meiotic germ cells (spermatogonia). ENU-treated males are crossed to wild ...

A genetic screen is screen is a laboratory procedure ... Mutations can be introduced into an organism's genome by exposing the organism to a mutagen, which is an agent that changes the DNA.

5. Easier to introduce genetic changes Introducing genetic changes in zebrafish is straightforward using chemical mutagens and other tools such as CRISPR. Zebrafish are able to withstand much higher ...

These worms don’t seem to give a damn about radiation Researchers subjected the worms to rigorous genetic analysis, including genome sequencing and tolerance tests with chemical mutagens in the lab.
