Genetic manipulation
Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism. Gene manipulation is also sometimes called the genetic engineering. It is a general term for any method which manipulate with the genetic material. Gene manipulation includes gene splicing, use of recombinant DNA, forming of the monoclonal antibodies or PCR (polymerase chain reaction).

The nervous system is a collection of cells, tissues, and organs ( brain, spinal cord, nerves ) through which an organism receives information from its surroundings and then directs the organism to respond to the stimulus.
The organ that helps us to recall and analyse is
-
Muscles
-
Brain
-
Spinal cord
-
Nerve
The brain regulates an array of functions necessary for survival. The brain houses our mind and our memories. Most available evidence suggests that the functions of memory are carried out by the hippocampus and other related structures in the temporal lobe of the brain. The brain also helps in the analysis of various body functions.
