DNA History
DNA
was first discovered way back in 1869 by Johann Friedrich Miescher. He
called his molecule nuclein, but today we know that Miescher's nuclein was
actually DNA and RNA. It wasn't until the 1950's that DNA was determined
to be the genetic material. This was accomplished by two scientists,
Alfred Hershey and Martha Chase, who studied viral replication in
bacteria. But the "great" discovery was still to come in 1953 when James
Watson and Francis Crick discovered the three-dimensional structure of
DNA: a double helix (a double helix looks like a spiral
staircase).

ANSWER
Do animals have DNA? What about
Viruses?
ANSWER
If someone receives a heap of my
blood via a transfusion, and then then a DNA check (blood) is performed on
them will my DNA still be present, or does it just get "dissolved". Also
what about a bone marrow transplant, or limb replacement
??

Mapping the DNA with Dr Karl S. Kruszelnicki
We humans have invented the wheel, tamed fire, invented
income tax and got to the Moon and back. But if you believe the hype,
these accomplishments are nothing, compared to the fact that we have just
recently mapped most of the human DNA.
What does it all mean? This
latest research tells us that the human DNA is a strange thing. You can
look upon it as a 'History Book' - where the DNA tells the history of
where various creatures have invaded us and set up home. In another sense,
you can look on our human DNA as a 'Parts Manual' for growing arms and
legs, and organs. And in another sense, you can look upon the human DNA as
a 'Medical Text Book', with advice on how to fix various diseases. And of
course, as we learn more, we'll see the DNA in many more different
ways.

I was wondering if you could
tell me what the current thoughts are on viruses. Are they animals or are
they just strands of DNA?

RNA?
Is RNA like DNA?
ANSWER
I have been wondering why Thymine is
OK for DNA, but RNA insists on uracil instead. Is this because RNA is
single stranded...or why?

How can you clone an animal or a plant ?
Can DNA
be extracted from hair, and if so can we clone from this?
ANSWER
Now that mankind has an idea of the
human genome, instead of cloning, is it possible to synthesize the human
DNA in totality to create life without cloning?
ANSWER
Over the recent debate over cloning
for infertile couples, I was wondering why they don't just insert the
male's cells into a different man's spermatagonium so that the sperm would
be produced with the infertile male's DNA. Thus the child would be
produced as normal (mitochondrial DNA of the sperm never enters the ovum).
Why don't they do that instead of a complete clone?
ANSWER
I heard a while back that scientists
want to clone a 'tasmanian tiger' from a preserved specimen. How is it
possible to clone an extinct animal?

World's first
genetically altered babies born
July 1997: Things start to get really strange. Can a
person have two biological mothers? A woman gives birth with an egg that
is partly hers and partly another woman's. As women get older, their eggs
become less permeable to sperm. To get around that, scientists take the
outer layer of a younger woman's egg and combine it with the nucleus of
the older woman. Most of a person's genetic material resides in the
nucleus.
