In this article we will discuss about the process of T-DNA transfer. Once plant exudates activating expression of vir genes and Agrobacterium attach to the plant cells, the T-DNA region in the Ti plasmid undergo excision process to transfer into the plant cells. Excision process involves active participation of vir genes such as virD, virC and virE. Separation of single [...]
Gene transfer in cereals is becoming established at the backdrop of recombinant DNA technology. Until recently, gene transfer in plants was accomplished only through certain conventional methods like sexual hybridization. The entire scenario of transformation was changed after the advancement of genetic engineering. Utility of Agrobacterium tumeifaciens as biological vector was found to be successful among dicots. However, its potential [...]
The following points highlight the two types of gel electrophoresis. The types are: 1. Polyacrylamide Gel Electrophoresis 2. Agarose Gel Electrophoresis Gel electrophoresis is the novel technique in which nucleic acid (even proteins) molecules are separated based on the size differences when subjected to electric field. In electrophoresis, the rate of migration in electric field depends on the field, net [...]
