   Can someone please tell me if this statement is true? (From Science
on Trial, by Douglas J. Futuyma - 1982, pp. 23-43). I've read parts of
The Origin of Species but don't own a copy:

I ran across a section in a college biology textbook titled "The
Nucleus: Control Center for the Cell."
I think this is a common way to view the nucleus and its DNA content.
These have been called the "brain" of cellular operations, or the master

Pip in a July response said,
But, now that I think more about it, those few sequences that do
exhibit function are probably all sequences with a fixed secondary
structure.  That is, they are the sequences that you would consider

PIP in a June post said this about replication:
But there is another solution.  Anchor one strand to one membrane and

philosophical
take (on mainly "evolutionary psychobiology type" aspects of) What Is going

Dear newsgroup readers,
I wrote an article which I want to submit to an scientific journal. But
I still have some questions. Also am I curious what you think of the
