DNA stores a cell’s genetic information. During interphase, DNA replicates (makes a copy of itself). That's why during Prophase, there are already 2 copies of DNA (2 sister chromatids) connected together at the centromere. This is still considered one chromosome, but now it has twice as much genetic material. How does this help explain why daughter cells are identical after mitosis?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
