Answer: grafting technique for plant genetic changes has been used since ancient time. In this two different plants have been cut and joint together to make new variety. Grafting technique has been mentioned in different Chinese text and bible. With the help of grafting stress tolerated plant has been generated, that can survive in stress condition. In the grafting shoot of one plant and root of one plant joined and grafted plant which survive are selected

selective breeding Made the green revolution in India, in this desired plant trait is achieved through the selected parent plant, after further generation of breed the desired plant is selected. We can get the desirable characterstics of plant, high yield variety seeds has been producing in India by selective breeding.

genetic modification can allow to produce insect resistant, drought resistant, high nutritionally valued plant, vaccine in plant which in traditional method we are unable to do.

gene cloning: to produce genetically modified plant

Example of genetically modified plant:

1) BT cotton & BT Brinjal

2) golden rice

3)soyabean

4) papaya

modern neuroscience, which has revealed the "plasticity" of the human brain, shows that our habitual practices can actually change our neuronal structures. The brains of illiterate people, for example, are structurally different from those of people who can read. So if the technology and its concomitant requirement to learn to read – could shape human brains, then surely it's logical to assume that our addiction to networking technology will do something similar? Do you agree?

Please summarize this article in 250-300 words. The economy has changed, and with these changes our communities must adapt themselves to some new realities. Traditionally, economic development, rooted in the post-World War II era, attempted to build our export base by subsidizing firms to locate manufacturing employment in our communities. This was fueled by cheap inputs—land and labor, national-scale competition, and low-skilled workers. Recruitment of industry received the most resources based on the potential to have significant impacts on the...

I feel that the government has made it too easy for our youth! During the time that most of use grew up we were not spoon fed on how to work on certain skills or were given help when finding employment. Making our youth more independent helps develop their futures as past struggles only make them stronger. Making it easy for youths will only make them ill prepared when they are faced with a real world situation once they are...

During the past several decade's significant progress has been made in our understanding of the process of DNA replication in eukaryotes.  Although the basic mechanisms of replication are similar to prokaryotes, significant differences are also apparent.  In contrast to prokaryotes where a single DNA directed DNA polymerase (pol III) catalyzes the formation of both leading and lagging strands, two distinct DNA directed DNA polymerases catalyze leading and lagging strand syntheses in eukaryotes. The features of these two replicates are listed below. Pol...
