Subject line refers to an article in the Nov 2003 issue of Scientific
American, some of you may be interested in reading it, if you haven>t
already. It touches on some of the things we have been discussing
on this newsgroup over the years re bold genetic engineering.
"Overview/Hidden genes:
- Geneticists have long focused on just the small part of DNA that
contains blueprints for proteins. The remainder - in humans 98 % of
the DNA - was often dismissed as junk. But the discovery of many
hidden genes that work through RNA rather than protein, has overturned
that assumption.
- These RNA-only genes tend to be short and difficult to identify. But
some of them play major roles in the health and development of plants
and animals.
- Active forms of RNA also help to regulate a separate "epigenetic"
layer of heritable information that resides in the the chromosomes but
outside the DNA sequence." |

If you want something to illustrate your point callipyge in sheep will do[/quote]
nicely.

It still doesn>t create any more risks than happen in normal unmonitored
crop breeding that that has brought us a host of problems that actually
caused harm in real people. There is nothing to keep me from dousing wheat
with mutigens or zapping it with X Rays and breeding my own variety and
selling it.

Huh? Is the callipyge mutation in sheep not within an ORF? |
