GMO'S Flashcards
What is the meaning of GMO
Genetic modification of organisms
Genetically modified crops of GM may produce higher food crop yields, but…..
scientists believe they may also create environmental problems.
What does the nucleus of the cell contain?
information that will allow the cell to copy itself.
Where is this information found?
The information is found on chromosomes.
What does each chromosome contain
Each chromosome contains many genes. Each gene is responsible for some feature of the organism it comes from.
eg. chromosomes contain genes that determine such things as the colour of your
eyes.
What is genetic engineering? and what is this technique used for?
Scientists can take the gene for a particular feature of one organism and insert it into the chromosomes of another. This is called genetic engineering. This technique is used to alter the characteristics of food crops, producing genetically modified (GM) crops.

Using genetic engineering, what could become possible?
- make the crop more resistant to disease.
- make the crop more resistant to drought.
- increase the yield of the crop.
What do scientists say about gmo crops
They say that GM crops could :
- alter the flavour of the food made from them.
- cross-pollinate with wild species.
Give the origin story of beta carotene cuz it’s their world and you’re just living in it
Scientists have added a gene to wild rice to make a strain of rice that produces a substance called beta-carotene. Beta-carotene gives wild rice a golden colour. It is needed by humans in order to make more vitamin A.
