Which of the following is true about the evolution of the genetic code?

0 votes

 

The organisms on the tree of life are unique because they use different genetic codes.

The common ancestor of all species living today used a very different genetic code.

The genetic code is random with respect to the ability of organisms to survive and reproduce offspring.

The existing genetic code is structured in a way that efficiently minimizes the phenotypic effects of small changes in DNA and errors during translation.
