    "Not all genetic information is stored using the genetic code"

    Came across this sentence in Wiki

    http://en.wikipedia.org/wiki/Genetic...NA_codon_table

    But unfortunately no explanation

    Does anyone know what are the other established mechanisms?

    thanks

    Zero

    The very next sentence in the article has the information that you seek.

    You could also add other things, such as RNAs that are not translated into proteins.

    Nope, not in context of that article.


    Apart from the epigenetics stuff that I mentioned previously, there isn't any other way of passing information from generation to generation using the medium of a fixed nucleic acid sequence (not off the top of my head at least). Metabolic and regulatory states (dictated by the environment) could maybe be inherited, but I don't think that's the sort of thing you're looking for.

    You may dig this talk by Craig Mello. He explains how information is stored sort of three dimensionally in the interactions between proteins, RNA molecules, etcetera. It's not as simple as "your genes are encoded in your DNA."

    "genetic code" only applies for protein-coding genes. Genes and other DNA regions that don't encode proteins also participate in regulation and the overall cellular function.
