INTRODUCTION
• Genetic Engineering is a field of engineering that deals with genes and DNA and their combination to get some specified traits. It is used by scientists to improve or modify the traits of an individual organism.
• Genetic engineering, which is also called genetic modification is a process of insertion of new DNA to a living organism through artificial methods.
• Genetic Engineering is a process in which a gene is physically removed from an organism and is inserted into another organism which now expresses the qualities given by that gene.
• A genetically modifies organism is generally referred to as a GMO that is genetically modifies organism. A GMO can be anything-a plant, an animal, a microorganism or any other organism which is genetically modified in a laboratory.
1.1 TYPES OF GENETIC ENGINEERING
Analytical Genetic Engineering
Under this branch of genetic engineering effective genetic models are created using computer based software. Under this, computer software are used to verify if the theoretically studied combinations would be a success or not before actually bringing it in practice. This is a trial and error method which reduces risks.
Applied Genetic Engineering
Applied genetic engineering is the practical application of genetic engineering tools. It is the process of manipulating the genes of organisms for making their genetic copies. The two examples of applied genetic engineering are cloning and transgenesis. Cloning on one hand, has always
Genetic Engineering is a fairly simple process that revolves around DNA. DNA, or deoxyribonucleic acid, is a molecule located in the nucleus
Genetic engineering is the deliberate modification of the characteristics of an organism by manipulating its genetic material. “If life is made of up of the same “stuff,” it should be easy to mix and match deoxyribonucleic acid from different organisms. All you have to do is cut out the DNA (gene) you want from one organism, and insert it into a new organism. This process is called genetic engineering. How to cut DNA: There are special tools that can be used to cut DNA called restriction enzymes, also known as DNA scissors, in order to combine DNA with different living things. Restriction enzymes are molecules that speed up the reaction that cuts DNA.

Genetic engineering is basically modifying and changing genes in people, animals, and fruits and vegetables it is something that is a good change for everyone.
Genetic engineering is the process of manipulating genes by adding new DNA or modifying the genome (which is a made of DNA) to add new beneficial traits in that organism using biotechnology. It removes the DNA from one organism and transfers into another organism. This changes the actions of the genes to serve human goals. DNA plays a huge role in this process. It contains human’s unique genetic code and also hold the instruction to make the proteins in the body.
Lets start by looking at the cell and the source of heritable traits. We know that all organisms are made up by cells and that new cells can only spring from existing cells. Cell growth depends upon the production of new cells and within each cell exists DNA. DNA contains the hereditary instructions need for each organism to grow and develop. Every
Genetic engineering is a very young technology. It is the modification of the traits and characteristics of an organism by changing the DNA of the organism. DNA is seen as a universal language because the code means the same thing in all species of animals. So when a trait is taken from one individual and added to the genome of another individual it has the ability
Genetic engineering involves the transfer of foreign genes into the cells of animals or plants at an early stage in their development so that they develop with desired characteristics.
Genetic engineering is the process whereby new DNA is added or existing DNA is altered in an organism 's genome. This may involve changing one base pair (A-T or C-G) or deleting entire sections of DNA or adding additional copies of a gene. This results in creating new traits that were not previously present in the organism’s genome. This is done to selectively breed desired traits or to create plants with increased resistance to pesticides and increased tolerance to herbicides. For example insulin is a protein that regulates sugar content in our blood and is produced normally in the pancreas. Genetic engineering is used to produce a form of insulin that is similar to yeast and bacterial cells. This genetically engineered insulin is called
Genetic engineering is a process that is able to alter the genetic sequence in the DNA of an organism’s structure. What
Modern technology has changed rapidly over the years, one of these innovations is genetic engineering. Genetic engineering is the deliberate modification of characteristics of an organism by manipulating its genetic material. it is a set of biotechnologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. Genetic engineering techniques have been applied in numerous fields including research, agriculture, industrial biotechnology, and medicine. Genetic engineering can be used for many manipulations in one 's genes. Particularly, it may be used for changing the sequence of genes so that if a person 's DNA has a gene for a certain disease it
Genetic engineering alters the genetic makeup of an organism using techniques that introduce heritable material prepared outside the organism either directly into the host or into a cell that is then fused or hybridised with the host.[1] This involves using recombinant nucleic acid (DNA or RNA) techniques to form new combinations of heritable genetic material followed by the incorporation of that material either indirectly through a vector system or directly through micro-injection, macro-injection and micro-encapsulation techniques. Genetic engineering does not include traditional animal and plant breeding, in vitro fertilisation, induction of polyploidy, mutagenesis and cell fusion techniques that do not use recombinant nucleic acids or a genetically modified organism in the process.[1] Cloning and stem cell research, although not considered genetic engineering,[2] are closely related and
Genetic engineering is a relatively new thing in early stages of development (Cummins 1). Genetically engineering something is done by altering or disrupting the genetic makeup. Some examples are microorganisms, plants, fish, trees, humans, and other animals (Cummins 1). Gene engineers move, get rid of, and add genetic material to something. There is even human genes and animal genes added to the DNA of other animals and plants, creating unimaginable life forms (Cummins 1). The products that are genetically modified currently are soybeans and soy oil, corn, potatoes, squash, canola oil, cottonseed oil, papaya,
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. Many problems have come with genetic engineering but it has made a big revolution in the world. We genetically engineer animals, food, plants, and more. Animals are one of the most popular species to be genetically engineered. One of the most famous animals to be genetically engineered is Dolly, the sheep. Dolly was one of the first mammals to be genetically engineered. Humans have tried to genetically engineer other humans over several year but all attempts have failed. Although it is said that if humans were cloned using the same method that was used on Dolly then human
Genetic engineering has to do with manipulating organisms and DNA to create body characteristics. The practice of genetic DNA has shown an increasing amount over the past years. The process of genetic enhancement involves manipulating organisms by using biotechnologies. The technique is by removing a DNA from one life form and transferring it to another set of traits or organism. Certain barriers are conquered, and the procedure involves changing a form of cells, resulting from an improvement or developed organism. GMO which is a (Genetic Modified Organisms) is the operation done in a laboratory where DNA genetic from one particular species or animals is directly forced into another gene from an unrelated subject of plants or even animals.
