Even a 5-way ligation is possible. Try about 10 femtomol of each fragment
in a 10 ul ligation reaction, overnight with about 1 Weiss unit ligase. I
don't think there is anything gained by ligating some segments separately.
You should be getting 10's to 100's of clones with anywhere up to 95%
being correct.
