Or - d'oh! - telomerase could be used to normalize the chromosomes before
ignition and liftoff. Or an hTERT package (human telomerase reverse
transcriptase, the catalytic component of telomerase) could be inveigled in
to *ensure* that telomerase stays active and kicking in all cells in the
new beastie, which might therefore become immortal at a blow - until it
dies of cancer, of course. But we need to fix cancers anyway...
Funny how these just-next-step extrapolations are always missing from news
reports (and possibly from the mouths of cautious scientists).
