chimera check

A chimeric sequence, or chimera for short, is a sequence comprised of two or more phylogenetically distinct parent sequences. Chimeras are usually PCR artifacts thought to occur when a prematurely terminated amplicon reanneals to a foreign DNA strand and is copied to completion in the following PCR cycles. The point at which the chimeric sequence changes from one parent to the next is called the breakpoint or conversion point
