[BioC] fastest way to get a gene list having certain GO term

[Duke]

Hi folks,

I need some statistics for a certain GO term (for example, "DNA 
binding"), and I wonder what is the fastest way to archive the latest 
list of genes having that specific GO term. There are now a number of GO 
packages and I would like to hear/learn your experience regarding 
various different packages.

Thank you in advance,

D.
