GENETIC ENGINEERING
This is a technology that involves the manipulation of the genotype of an organism to get the desired trait. It also involves the transfer of gene coding for the desired trait from one organism to another.
Application of Genetic Engineering
Pharmaceutical industries:
- Making of hormones e.g. Human insulin and human growth hormone.
- Enzymes e.g. Alph-Anti-Trypsin (AAT) used to treat emphysema. (c) Proteins.
- Drugs and vaccines.
Agricultural industries:
- Transgenic animals and plants are produced which are also called Genetically Modified Organisms (GMO’s).
- A variety of tomato with improved paste and a longer shell life.
- Sheep for producing desired proteins in milk.
- Plants resistant to pests and diseases.
Cloning
- This is the making of identical copies of genes, DNA and whole organisms.
- Cloning is used in plants – that is tissue culture e.g. in development of various varieties of bananas and Eucalyptus trees.
- The first mammal to be cloned successfully was Dolly – the sheep.
- A nucleus from the cell obtained from the udder of the sheep was inserted in an unfertilized egg without a nucleus.
- This zygote was introduced into the uterus of a sheep and developed to full term.
Gene therapy
- Involves injecting genes into patients of certain diseases e.g. Parkinson’s diseases.
- The injected gene alters metabolism to bring about the cure of the disease.

We built School Portal NG to specially serve as an alternative means to provide free education for the less-privileged children or children born to low-income earners, adults who otherwise cannot afford to finance their way through school.
Building & maintaining an elearning portal is very expensive, but this portal is free. Help to keep this learning portal free by donating or supporting us. We accept donations, grants, sponsorships & support to help reach out to more children. Thank you so much. Click here to donate
