Is the DNA the same in every organism? Would the DNA of a paramecium be the same as the DNA of an onion?

The chemical makeup of DNA is the same in every organism, ie. it is made from the same basic chemicals. It is the order of the bases (ATC and G) that form a code that makes one organism different from another. It is kind of like our alphabet. All words in our language are made up of a grouping of the same 26 letters. We put them in different orders and of different lengths to make different words with different meanings. DNA is similar except that the code is made of only four letters. Putting them in different orders and of different lengths make new genes that code for different proteins.
