what is DNA Replication ??

DNA replication or DNA synthesis, the double- stranded DNA before cell division is the process of copying . new DNA strands are copied almost exactly the same , but from time to time due to errors in replication is not a perfect copy (see mutation) , and the results of both the helix consists of an old and a new thread . It is called semi- conservative replication . DNA replication consists of three steps : initiation , two recovery and termination
Recombinant DNA ..
Recombinant DNA or Recombinant DNA technologyOften obtained from different biological species of DNA molecules , genetic engineering and the cessation of DNA fragments obtained from different biological processes and combining the results of this process produced the name given to the new DNA molecules .
Recombinant DNA technology is used in many fields .
Recombinant DNA technology is used in many fields .

Genetic recombination events artificially realization is based on recombinant DNA technology ( rDNA ), the first work in 1973 has started , and 80 in the giant steps forward , and today, the name most frequently mentioned , and molecular genetic revolution has created a science has become .
