Why does life on Earth synthesize DNA in the direction it does?
o It's the only chemically possible way to polymerize nucleotides
o It's the only way that prevents an energy deficit following proofreading
o It's the most energy-efficient way of polymerizing nucleotide chains
o It's the only way that allows the DNA to be aligned in an anti-parallel orientation
o It's the only way that allows for hydrogen bonding between base pairs
