Licensing factor is necessary for initiation of replication at each origin. Licensing factor is present in the nucleus prior to replication, but is removed, inactivated, or destroyed by replication. Initiation of another replication cycle becomes possible only after licensing factor reenters the nucleus after mitosis.

SSR alleles differ in length.

Left and right primers correspond to unique sequences that flank the SSR locus.

PCR-amplification of two alleles of an SSR locus.

Gel electrophoresis distinguishes the alleles from each other.
