Basic Question-Chromasome Pairs

[Thomas Han]

What is the number of chromosome pairs for the primates? Or where is there a
good source of this information on the net?
Thanks Very much+ACE-

It depends on the primate! The orang.,gorilla, and chimp. all have 48
chromosomes or 24 pairs. Humans have 46 or 23 pairs.

There's an old but verg good pictoral legacy of human evolution if you have
access to a library with the journal science.

If you want other primate chromosome numbers I suggest you go to your server's
web search engine and type in primate chromosome numbers or variations thereof.
Hope this helps

Yockey, Hubert P. "An Application of Information Theory to the Central
Dogma and the Sequence Hypothesis" _Journal of Theoretical Biology_ 46:
369-406 (1974). On 371:
The vast majority of the sequences in the ensemble of all sequences
of length _N_, of letters of a written language have no assigned
meaning or specificity. The same is true of sequences of digits
zero through nine and of musical notes. However, embedded in the
ensemble of all such sequences are, say, a play by Sophocles, the
lost works of Aristotle.... By the same token the protein
sequences of length _N_, which carry specificity, are embedded in
the ensemble of all amino acids sequences of length _N_. Those
sequences which carry specificity are a tiny fraction of the
ensemble.

Statement: "Those amino acid sequences of length N=101 thru N=1010 that
carry specificity are a tiny fraction of the ensemble of all amino acid
sequences of length N=101 thru N=1010." Ballpark answers to the
questions below would help me determine the validity of this statement.

Of all possible amino acid sequences of length 101, what proportion of
those sequences will be functional proteins of some sort? 1/9th?
1 out of every 2,000? 1/10^17th? 1 out of every 10^24? 1/10^80th?
What?

Same question, this time for amino acid sequences of length 202?
Of length 303?
Of length 404?
Of length 505?
Of length 606?
Of length 707?
Of length 808?
Of length 909?
Of length 1010?

Also, how long is the biggest functional amino acid sequence of which
you're aware?; of all possible amino acid sequences of that length, what
proportion of those sequences will be functional proteins of some sort?
