In recombinant dna technology stem cells are important to biological researchers because they can be used to generate virtually any type of specialized cell in the human body a number of objections have been raised against reproductive human cloning.
The discovery of two types of enzymes in 1970s solved the problem of gene cloning one is the restriction endonuclease and the other one is dna ligase the restriction endonuclease or restriction.
