what does it mean when scientists say that living organisms share a universal genetic code?

Question

zale101 · Answer

That means that living organism share similar ancestory long long time ago, this means their genetic code is related. Have you studied about the DNA squences and the 4 bases Adenine Thymine Cytosine Guanine. They all share similar similar DNA bases. If organism share genetic codes, that means the DNA and RNA-only organisms have only a choice of four different "letters" in the code.
