The amount of light is referred to as the fluence, which is defined as the total number of photons impinging on a unit surface area. Total fluence = fluence rate × the length of time

Energy derived from absorbed light is used to reverse the photoreaction that caused the lesion.  The two chromophores in E. coli photolyase (Mr 54,000), N5,N10 methenyltetrahydrofolylpolyglutamate (MTHFpolyGlu) and FADH, perform complementary functions

In some cases, the various heterochromatic regions, especially those associated with centromeres, aggregate into a densely staining chromocenter.

The common form of heterochromatin that always remains heterochromatic is called constitutive heterochromatin. 

It is permanently condensed. 

It replicates late in S phase and has a reduced frequency of genetic recombination relative to euchromatic gene rich areas of the genome.
