Report on frog cloning
Understand the Problem
The user is requesting a report on frog cloning, likely for a college project. This is a request for information on the topic of frog cloning.
Answer
John Gurdon successfully cloned a frog by nuclear transfer, publishing his findings in 1962.
The first cloning of a frog was successfully performed by John Gurdon. In 1962, he published a paper about producing normal tadpoles from the nuclei of intestinal epithelium cells of Xenopus laevis.

More Information
John Gurdon's work was revolutionary, showing that the DNA in specialized cells could still direct the development of a whole organism. This challenged the idea that cells lose genetic information as they specialize.
Tips
It's important to remember the specific type of experiment Gurdon conducted: nuclear transfer. This involves taking the nucleus from a body cell and placing it into an egg cell that has had its own nucleus removed.
