Somebody please explain ...
I have an oligo (A) (non-phosphorylated in 5') of ~ 100 bases.
I have its complement (B) with two over hangs (~4 bases each) on both he sides(5' and 3').
the overhangs on the B are palindromic. as in the 5' overhang is palindromic to itself.
I annealed both of them.
phosphorylated the sample.
added ligase
after ligation, when i ran it on the gel, i saw only monomers and dimers.
Why is this so ?
y not other multimers ?
did i go wrong sumwhere ?
please help
