Заткнись и жри бамбук.
Идет баржа Белая!..
Длинная, как!..
Ромашки!.. Ну просто!..
Salmon SPERM DNA is a very widely used source of cheap DNA. Sperm in many fishes is produced in massive amounts, and is a liquid with a very high density of DNA (has many sperm cells that are almost just a nucleus). It could be harvested without killing the fishes but I guess that the sperm is extracted from fishes that are already harvested for the food industry.
