Genetic engineering technology is the genetic modification of an organism to introduce desirable characteristics. First introduced between 1971 and 1973, it encompasses recombinant DNA technology, genetically modified organisms (GMO), and gene therapy.
How bacterial plasmid DNA and human insulin genes are cut, joined, cloned, and harvested.
Genetic engineering is the term used for the genetic modification of an organism. It was first introduced around 1971–1973 and is known as genetic engineering science.
Genetic engineering allows scientists to transfer specific genes between different organisms. It is commonly related to recombinant DNA technology, genetically modified organisms (GMO), and gene therapy.
Recombinant DNA technology combines DNA from two different species to produce a new genetic characteristic. Examples include plant DNA combined with bacterial DNA, human DNA combined with fungal DNA to create hybrid DNA, and the human insulin gene combined with bacterial plasmid DNA to produce human insulin for diabetes mellitus patients.
A GMO is an organism (plant, animal, bacteria, or virus) that has been genetically modified for a particular purpose. It combines genes from two different species and produces new traits that may not be achievable through traditional selective breeding or crossover processes.
Recombinant DNA technology turns bacteria into biological factories.
Desirable characteristics developed in genetically modified crops.
Applications of GMO in agriculture include paddy, maize, and palm oil cultivation. Desirable characteristics developed include:
Genetically modified crops can produce larger fruits, increasing harvest yield.
GMO crops can be enhanced to contain more nutrients for consumers.
Modified crops resist pests and diseases, reducing crop damage.
Pest-resistant crops reduce the need for chemical pesticides, thereby decreasing environmental pollution.
Advantages and disadvantages of genetic engineering.
Moral and legal standards protect human welfare.
Research must be conducted with high integrity so that it does not violate moral and religious principles. It must be directed toward beneficial solutions, such as treating diseases like diabetes mellitus via insulin synthesis and solving global issues like food shortages and crop damage.
Strict laws and regulations must be enforced to regulate research, educate scientists, and prevent unethical misuse. Experiments must respect religious and moral sensitivities.

What is the specific enzyme used to cut both the human insulin gene and the bacterial plasmid DNA in recombinant DNA technology?
Give two commercial traits desired in agricultural crops produced through genetic modification.
Why must strict ethics and laws be enforced in genetic engineering research?
Genetic engineering is identical to traditional selective breeding.
Traditional breeding crosses organisms within closely related species, whereas genetic engineering can transfer genes across completely different kingdoms, such as animal genes into plants or human genes into bacteria.
Recombinant bacteria produce bacterial versions of insulin.
Because they carry the human insulin gene, recombinant bacteria produce human insulin identical to that naturally produced in the human pancreas.
1 Which of the following is an advantage of genetically modified crops in agriculture?
2 Where do recombinant bacteria multiply to produce large amounts of human insulin?
3 The specific enzyme used to cut human DNA and plasmid DNA during recombinant DNA technology is the enzyme.
4 An organism whose genetic material has been altered by combining genes from two different species is called a Genetically Organism.
