The correct answer for the given question above would be the third option. The statement about the genetic code that is not true is that, each species of organisms has its own unique genetic code. Genetic codes are universal among organisms, even though there is some slight exception of some. The universal genetic code is a common language for almost all organisms to translate DNA and RNA to amino acid sequence sequences of protein.
