Nope. You have to have the centromeres for cell division. It's part of the signaling command coding structure. The telomere protects against genetic data deterioration via redunduncy, but it's STILL GENETIC CODE!
I guess your statement that “all DNA has the genetic code” was your idiotic way of claiming that all DNA is functional.
Now you are insisting that all functionality is some sort of “code” and that is a misuse of the word, as well as being rather idiotic. Must I ask you again if you consider a philips head screwdriver fitting into a philips head screw as some sort of “code”?
A centromere is not part of the genetic code, but it does have functionality. All functionality is not a code, and only if it is translatable into an amino acid sequence is it the GENETIC code.
Short repeat DNA has no known function, and it is also not part of the genetic code. And again I repeat to you, because you seem to be having a real hard time figuring it out, functionality does not imply a “code”.
