Genetically Modified Organisms (GMOs)

And how they are important in the 21st century

By: SB


What are gmos

What Are GMOs?

  • GMOs are organisms who have had their genetic makeup altered to give them new characteristics or traits.

  • Can be used to greatly improve all types of organisms

  • Bacterial Cells

  • Plants

  • Animals

  • Humans


How they re created

How They’re Created

  • Desired gene is isolated and cut with restriction enzymes

  • Replicated many times through PCR or bacterial plasmids.

  • 2 ways of getting the gene into the cell…

    - A vector (bacterial plasmids or viruses)

    - Shotgun method (bio-ballistics)

  • Done in the embryonic stem cells.

  • 2 types of genetic engineering

    - Positive eugenics

    - Negative eugenics

Gm bacterial cells

GM Bacterial Cells

  • Antibiotic resistant bacteria made to help find new drugs

  • Human genes added to bacteria to produce human hormones that can treat certain diseases or disorders.

  • Certain bacteria can be used to benefit our environment.


Genetically modified plants

Genetically Modified Plants

  • Enhances the taste and quality of fruits, vegetables, grains, etc.

  • Takes less time to ripen and stays ripe longer

  • Greater resistance to disease, insects and herbicides

  • Increases the yield of the crop

Genetically modified animals

Genetically Modified Animals

Agriculture

  • Better yield of meat, eggs and milk

  • Increased resistance, hardiness and productivity

    Pharming

  • Certain animals produce substances that are useful in treating human patients

    Medical Research

  • Helps to determine what certain genes do

  • Experiments done on animals with human diseases allow for discoveries of new drugs


Genetically modified humans

Genetically Modified Humans

  • Eradicates all genetic diseases.

  • All physical traits of a person can be modified to be what the parents wish.

  • It’s believed that psychological and social characteristics can be altered as well.

  • Improve health and lifespan.


Pertinence in the 21 st century

Pertinence in the 21st Century

  • The use of genetically modified crops and animals to help solve world hunger problems

  • Using genetically modified bacteria or animals in the field of medical research to find or develop new drugs

  • Genetic engineering of humans to eradicate genetic diseases

  • Germline manipulation of humans to produce “designer babies”
