A Correct answer
Explanation

Rosie was the name of the first transgenic cow. Golden rice is an improved variety of genetically engineered rice with high content of Vitamin A. Bt cotton is transgenic cotton created by inserting a crystal protein gene (cry) from the soil bacterium Bacillus thuringiensis into the genome of various cotton cultivars. Radioactive isotopes often behave as DNA probes which are used to identify the various sequences of DNA.
