I saw a news item that stated that Dolly may actually be a 5 year sheep, not a
child because she may have inherited her "mother's" older genes. I have heard
that DNA damage resulting from an inability to replicate clearly may be one
factor in the aging process, but was surprised to hear that the "strands'
actually break apart and become shorter.

Any truth to this?

Many thanks!!
