DNase and DMS, other reagents are commonly used to footprint protein–DNA complexes by breaking DNA except where it is protected by bound proteins. For example, organometallic complexes containing copper or iron act by generating hydroxyl radicals that attack and break DNA strands.

Species diversity - Number of species

Western Ghats have greater amphibian species diversity than the Eastern Ghats. 

The overall richness of species is concentrated in equatorial regions and tends to decrease as one moves from equatorial to polar regions.India has 390 different mammals (rated eight highest in the world); 1,232 species of birds (eighth in the world); 456 species of reptiles (fifth in the world) and 45,000 plant species, of which most are angiosperms, (fifteenth in the world)

If a stem cell divides asymmetrically, produce two types of cells (a stem cell & a developmentally committed cell) are produced at each division, is called the single stem cell asymmetry.
