Which of the following is untrue about DCA?

It stands for Divide-and-Conquer Alignment

It works by breaking each of the sequences into two smaller sections

The breaking points during the process are determined based on regional similarity of the sequences

If the sections are not short enough, further divisions are restricted as well
