Cloning

Anyone ever having a hope of a sci-fi cloning should be aware of mosiacism – that the DNA of one of your cells may be radically different from the DNA of another of your cells.

As all of your cells are copies from cells that have come before, any change along the way to your present body is inherited, but only by the cells created from that change. A study found at least 5 lineages in a test-subject and many more versions along the way.

Having just found out about telomeres and potential influences by environmental factors, and still reeling from learning about DNA methylation, I think my understanding of DNA has been mediocre at best.
