theory question

Hi,

A question about minor scales and the chords which belongs to a certain 
'step' in the scale.

I've learned when major scale:

step:
I: maj7
II:  min7
III: min7
IV: maj7
V: dominant 7
VI: min7
VII: -7

But what when it is a minor scale? For example E minor? Which type of 
chords belongs to the 7 steps?

thanks in advance.
