What are the Risks of Cloning? - 1 views

  • Cloning animals through somatic cell nuclear transfer is simply inefficient. The success rate ranges from 0.1 percent to 3 percent, which means that for every 1000 tries, only one to 30 clones are made. Or you can look at it as 970 to 999 failures in 1000 tries.

      There is such a high failure rate, resulting in cloning animals. What we hear of in the news are only the few attempts that actually worked, but there are so many cloning experiments that have failed and here are the statistics. 
  • The enucleated egg and the transferred nucleus may not be compatible An egg with a newly transferred nucleus may not begin to divide or develop properly Implantation of the embryo into the surrogate mother might fail The pregnancy itself might fail

HowStuffWorks "DNA Replication" - 0 views

  • A subunit of the DNA polymerase proofreads the new DNA
  • Before a cell can reproduce, it must first replicate, or make a copy of, its DNA.
  • DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same.
