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.

MDM2 levels in the cytoplasm are controlled by

ATR and p14ARF (p19ARF in the mouse), sequesters it in the nucleolus, where it cannot access p53.
