HELP NEEDED: How you pronounce pUC?

[johanna preiszner]

The question may be crazy for everyone. I have a colleague, who insists,
that everyone she knows pronounce it as "puc" [pak]. I am not sure it is the
right way. I have never ever heard other way than [pi-ju-si']. Both of us is
in cloning for years, and coming from different places. Please help us,
because we are fighting, and getting tired of this. Make your vote!!
Thanks, Hanna
