The group's motto is: If Everyone Hunts Toads, Soon Got interested in toads even before seeing them. Geelong is in southern Victoria, an area that the toads have not yet taken over. But one day at a conference, he was sitting next to a molecular biologist who was studying the toads, who told him that despite their best efforts, the toads continued to spread. She noticed this with great distress and regretted that there were no new ways to address it, recalls. Well, I sat down and started thinking.
Here's how I reasoned: the toxin is a by-product of the toad's metabolism. This means that UK Mobile Number List enzymes are involved in their production, and the enzymes must have genes that encode them. At the same time, we have the tools to turn off genes. So, can't we turn off the genes responsible for toxin production? To help, young scientist Caitlin Cooper, with shoulder-length chestnut hair and an infectious smile, came to Australia from Massachusetts. No one had edited the aga toad genome before, so Cooper hadn't figured out how to do it yet.
It turned out that the toad eggs had to be cleaned and then pierced with a very thin straw, and it had to be before the cells started dividing. I've been practicing microinjection for a while, tell me. First, she decided to change the color of the toad. The key gene for skin pigmentation in toads (and humans, by the way) encodes the enzyme tyrosinase, which controls the production of melanin. The reasoning was that if this gene were switched off, the result would be light-colored toads, not dark-colored toads. She mixes several eggs and sperm in a Petri dish and places The relevant substances are injected into the resulting embryos, and then wait. Three unusually brightly colored tadpoles emerged. One of them died. The other two, both males, had grown into spotted toads.
