Homothetic rescaling of (human) chromatids.
Rescaling of chromatid C units into similar but smaller epsilon (epsilon) subunits is discussed. When subverted, these subunits are responsible for repositioning genes in different states of transcriptional accessibility via an analogy in miniature of more massive sister chromatid exchanges.
