From the speed of replication, it is evident that a mammalian genome could be replicated in 1 hour if all replicons functioned simultaneously. S phase actually lasts for 6 hours in a typical somatic cell, though, which implies that no more than 15% of the replicons are likely to be active at any given moment.

Solar radiation, in the form of short-wave energy, passes through the atmosphere to heat the Earth’s surface. 

Long-wave infrared energy is radiated back into the atmosphere. 

Most infrared energy is reflected by atmospheric gases, including carbon dioxide molecules, back to Earth, causing global temperatures to rise.
