Subject: Possible (nor or ever) to alter a male donor's DNA so the clone is female?

Dear Mad Scientists,

Is it possible (now or how long into the future) for the clone donor to be male 
and then alter his DNA so that the clone is female?

I actually need this for a science fiction short story I am writing for 
creative writing class.  Hope you don't mind.  I did do my homework and looked 
around the internet and the library.  I have answers to most of my questions 
except this one.

I guess I have some license to make up the science involved in a science 
fiction story.  But I'd like to know what the real science looks like anyway.

Thanks, thanks!
