Jack:
Youre talking about DNA as being structural, as well as having information?
Andrew: Absolutely.
That is the information. The structure is the message, is what I believe.
Jack:
With proteins Ive already learned that that is the case. These things
seem to be rather magical. Proteins often perform the role of messenger
and here we have the messenger also being part of the cement. Its
part of the wall.
Andrew: Oh, absolutely.
Jack:
Central dogma? Tell us what, what, what, what's the problem?
Andrew: First of
all, there's, there's two things wrong with it. Central and dogma, all
right. For many years it functioned -
Jack:
Tell us what it is.
Andrew: Well, it,
its an explanation chemical terms, of how heredity and how proteins are
made and this sort of thing. How heredity works and proteins are made.
The problem with it's not the center. If you take an egg for example;
an egg is a protein for the most part and you can take the nucleus out
where all the genes are, and the damn thing will develop for quite a time.
How do you explain all those cell divisions without DNA? It's interacting
with the proteins. "Without nucleic acid proteins have no past and without
proteins nucleic acids have no future".
Jack:
So what's the difference between them and the central dogma?
Andrew: Well the
central dogma says that we can predict all things based on knowing the
primary sequence of the nucleic acid.
Jack:
And you say?
Andrew: No! Absolutely
not! I gave you this example yesterday youd never predict that a
guy that didnt have the elastin gene which is a structural gene
for skin and for vessels and it makes them elastic would be a better musician.
You know, you, cant
Jack:
Just explain that again, for the sake of readers . A person with a tight
skin -
Andrew: Without elasticity
- the skin has no elasticity. The elastin gene product.
Jack:
That same gene which gives a person this condition, so that his or her
skin has no elasticity. Just that one gene also gives the person an ability
to play music really well.
Andrew: That's right.
And they do other things too.
Jack:
And all that comes from one single gene. The one gene has at least three
complete, seemingly unrelated messages. So in fact, were really
talking about surrealism here. What is life?
Andrew: What is life?
Life is a very specific and peculiar organization. Its extremely
complex in its organization. Features we associate with the living processes
include motility, propagation, homeostasis.
Jack:
What is homeostasis?
Andrew: The ability
to stay the way one is.
Jack:
A cell is alive, a virus is not alive?
Andrew: Thats
right.
Jack:
A bacterium is alive?
Andrew: Thats
right. And a piece of a cell is alive for a while, okay, even though it
doesnt have any nucleic acids in it.
Jack:
Because it replicates?
Andrew: No! It doesnt
replicate. you see. Its, thats where the, the idea of all
of these things being necessary characteristics or Aristotelian qualities
the predicate of the sentence, "What is life?" Life is, motility
and replication. The problem with that is that there are exceptions but
the exceptions are either time-shifted or materially shifted in some way
that would not constitute normal living processes. They occur in experimental
dishes or whatever. I mean they dont normally occur in the pageant
of evolution. I mean you have intact cells in other words you don't cut
em in half, okay. That contributes nothing to organic evolution to cut
a cell in half. But you cant say that, that piece of cytoplasm isnt
alive. After all it maintains homeostasis. You can in, in effect reduce
life.
Jack:
What will be the next thing which will make you feel, okay! That's an
achievement! I wanted to do that, and I've done it!
Andrew: I want to
cure melanoma. It's a cancer. It's a very deadly cancer. I've picked one
cancer because cancers are all different and even the same cancer is different
in different people. So, I've focussed now on melanoma for about 3 years
and we've gotten some inroads in understanding how its organized, its
structure if you will. So now we can begin perturbing it, or changing
it in certain ways and asking if we can actually stop it. And that's what
I came here to this meeting to discuss this ground state and how to articulate
it. This is the ground state and from the computer people and the physicists
here I've learned to call it, in their lingo.
Jack:
Halt state.
Andrew: The halt
state. I can make the analogy and its useful to make an analogy because
when you make an analogy then you can make a physical model, as Watson
and Crick did. I go back to the heroes. I always do.
Jack:
They're your heroes?
Andrew: Absolutely.
Jack:
Even though you contradict their -
Andrew: Yes.
Jack:
their dogma?
Andrew: Yes. Yes.
Because they made a model. And the model has been extremely useful in
employing millions of people for many years.
Jack:
What kind of a shot do you have at achieving your aim, curing melanoma,
do you think?
Andrew: Better than
average.
Jack:
Better than average?
Andrew: Better than
average, if I'm lucky and keep my head screwed on right and work very
hard, have good help - as you know I've had the last few years. I've been
fortunate the last few years. If I have those things then I think we can
cure cancer, I really do.
Jack:
Great.
Andrew: At least
this cancer, all right.
Jack:
Right! And, and that will help us to cure others?
Andrew: It invariably
will, because, I'm not going to say the same method may be used, but some
of the principles may be applicable.
Jack:
I wish to inform,our reading public, that, Dr. Andy Mitosis I beg
your pardon silly mistake, Dr, Andrew Maniotis - as of this moment is
lighting a cigarette. Thank you.
Andrew: [LAUGHTER]
