  I wanted to ask if it is anatomically possible for a slim woman to
have GG breasts? All the big breasted women I find over the net are
fat. Is breast size directly associated with fatness of other parts?
  If it's isn't, I would be grateful to anyone who can point me to

the human immune system rejects a new organ (if cloned from an unknown
person) as it doesnot accept the foreign dna.but, how come organs in
frog r cloned and transplanted among their species? what is the
difference betwwen the frog's immune system and human immune system?

Why can't existing stem cell lines be expanded by transplanting new
nuclei into "legal" stem cells?  Would such a cell be compatible with
the organism that provided a nucleus?  Would it still behave as a stem
cell?

Does the z-DNA conformation code for any genes, or is it part of any exons?

Certainly topics such as territoriality, xenophobia, kin selection and
aggression are part of evolutionary biology. They are aspects of our
biology which have persisted ever since Homo Sapiens have been around.
Evolutionary biology encompasses much more than just Homo Sapiens (which

Can someone help me in removing DNA from E.coli cell lysate.

A few days ago I watched a NOVA program on the variety of dogs with
talk of their evolution from that of wolves. Quite an interesting
program. However there are very many gaps of logic in the discussion
of how dogs came from wolves.

I'm deveolping a GM Technology talk for A-level students at a local
school.  Does anyone know some good topics to talk about.  I'm
thinking on the lines of GM food and drugs, like insulin.  Are there
any other areas that would be good to talk about.  This is my first

I'm very curious.
Do *any* animals have hearts on the right side? This may include even
fish, ocean floor volcanic ecosystem lifeforms, even insects (although

Hi, I wanted to ask about the notion of harnessing the immune system
