Importance of Gene Manipulation Techniques

Genetic modification allows changes in genes to transfer genetic material in different organisms. It is possible to introduce foreign genes into crop plants and express these in specific tissues. Transfer of genes can help to improve crop protection. Genetic modification can be done with various viral and non viral methods. Direct manipulation of DNA sequences can lead to different expression levels. Choosing the best method for gene delivery can be a difficult task, particularly to transfer genetic material in a proper way. This review highlights, basic mechanism and importance and differnet methods used for efficient gene delivery. Hence, understanding of intracellular machinery plays a crucial role for designing a more effective gene delivery environment.
