Recent advances in genetic engineering and re-

VIEWS: 99 PAGES: 4

Genetic engineering, also known as gene-splicing techniques and DNA recombinant technology, is based on the theory of molecular genetics, molecular biology and microbiology and modern methods as a means of genes from different sources according to pre-designed blueprint for building hybrids in vitro DNA molecules into living cells and then to change the genetic characteristics of the original biological, access to new varieties, production of new products.
