For many reasons:

-ethics..

-People are afraid to be cloned without their knowledge

-if hypothetically clones could be created... Pepole might clone a sick person and harvest the clones organs... A humans body has the ability to fight foreign subsatnces like pathogens. Sadly, this means our immune systems fight off foreign organs. That's why people don't live long after organ transplants and have to take immune suppressing drugs. Cloned organs would solve the problem but it woul kill the clone.

- then theres those ingnorant religious nuts who don't believe in evolution and don't wont humans playing God in fear of being punished by his/her/its hands. Which is stupid. If humans are going to be punished it'll be because their own ignorance and not because of god. The most likely end would be the suns radiation killing us because the ozone got completely distroyed

DNA replicaton begins when the two complementary DNA strands are separated. This is usually accomplished by special proteins that unwind the molecule and expose the nucleotide bases (imagining zipping down your sweater or whatever)

New complimentary DNA strands are then synthesized by pairing up original DNA with new nucleotides... for each strand

At the end of the process the cell has made to identical copies of all the biological information contained on the original, parental, DNA molecule, but the two new daughter DNA molecules are "Half old" and "Half new". Half the original DNA molecule is saved, or conserved in the daughter molecules. This is why the process is called semi-conservative.

See (http://www.brooklyn.cuny.edu/bc/ahp/BioInfo/REP/DR.Semi.html) for a visual!
