this was posted on another bionet newsgroup, and I
thought it would be of interest to some of
the readers of this newsgroup.

Three other yeast chromosome's were completed in 1994, thus there are
seven of the sixteen S. cerevisiae chromosomes in the databases.  A
few corrections from the above list.

  I      223Kb (under Keith's cutoff)
  II     807Kb
  III    315Kb
  V      569Kb
  VIII   563Kb
  IX     440Kb
  XI     666Kb

I believe few new large sequences will be deposited in the sequence
databases in one piece as the NCBI/EMBL/DDBJ are agreeing on a maximum
size of an entry.  I think this size will be around 350Kb.

For all the yeast chromosomes the SGD provides a file of the entire
chromosome sequence via gopher and anonymous ftp.
