Why are flanking sequences important.
3’ Homology is much more important than 5’ Homology. Thanks to this wonderful loophole, as long as 15-20 bases at the 3’ end of the primer are absolutely conserved from the target sequences, we can add up to ~30 bases to the 5’ end without negatively impacting the reaction.
