During early cleavage, each asymmetrical division produces:

• One founder cell (denoted AB, E, MS, C, and D) that produces differentiated descendants
• One stem cell (the P1–P4 lineage)

MARs are AT rich heterochromatic regions which contains cis-acting sites that regulate transcription, 5’ introns, and a recognition site for topoisomerase II is usually present in the MAR.

Each set of ter sites allows a replication fork into the termination region, but does not allow it out the other side.For example, replication fork 1 can pass through terC and terB into the region, but it cannot continue past terE, -D, and -A. This arrangement creates a "replication fork trap."
