I want to design a forward and reverse primer that include overhangs with restriction sites, with the dna used for restriction enzyme cloning.
If I want to send my dna to a synthesis company should I include the attached overhang with the restriction sites to the dna? Does it matter if the primers have the overhang of the dna within their sequence ?
From the sequence right at the end what bp sequence would be recommended I use for my primers if I want approx. 20-25bp for the primer?
See below for cDNA sequence:
Nde1 cut site: 5' ... CA|TATG ... '3'
Xho1 cut site: 3'...GAGCT|C...5'
cDNA with overhangs that have restriction sites, Ndel1 (5'->3') and Xho1 (3'->5')
