Transgenic species Flashcards
What is a transgenic species?
An organism that has been genetically modified to include genes from another species
This modification may give it new traits such as disease resistance or enhanced growth.
What are the steps involved in creating a transgenic species?
- Gene Selection and isolation
- Gene insertion into a vector
- Gene Transfer into an embryo
- Birth and screening
- Breeding & application
Each step is crucial for successful genetic modification.
What is gene insertion into a vector?
Putting the gene into a carrier (plasmid or virus) that has controlling components
This is an essential step in the process of genetic engineering.
What is the purpose of screening in the transgenic species creation process?
To select successful transgenic cells based on if the genetic trait works
For example, using UV light to test if a glow in the dark rabbit emits light.
What are some agricultural benefits of transgenic species?
- Improved growth
- Resistance to pests and diseases
- Increased nutrition
Crops like golden rice have extra vitamin A.
What environmental benefits do transgenic species offer?
Some can reduce the need for pesticides and herbicides, helping against pollution
This can lead to healthier ecosystems.
What medical advancements can transgenic species contribute to?
They can produce medicines such as insulin or vaccines at a lower price
This can improve access to essential medications.
True or False: Eating genetically modified food is universally accepted as safe.
False
There are ongoing debates and concerns about long-term health effects.
What ethical questions are raised by altering genes in animals?
Concerns about messing with nature and the beliefs of many people
This includes religious views on genetic modification.
What are some social concerns associated with transgenic species?
- Ethics
- Food safety
- Environmental risks
- Public distrust
These issues can affect public perception and acceptance.
What is a potential consequence of transgenic species escaping into the wild?
They could harm ecosystems and reduce biodiversity
This poses risks to natural habitats.
Fill in the blank: Transgenic species can create _______ which can make farmers dependent on expensive seeds.
superweeds
This can disrupt agricultural practices.
What dietary laws could be violated by inserting pig genes into a plant?
Some dietary laws in Judaism and Islam
This could raise significant ethical issues.
What is a key risk of changing an organism’s genes?
It might cause harm or unexpected problems
This includes potential harm to animals and the environment.
What are some benefits of genetic modification in agriculture?
- Better crop growth
- Protection from diseases
- Improved nutritional content
These advancements can help address food security.
What is the importance of considering negative effects of genetic modification?
To ensure it is used responsibly
Awareness of risks helps in making informed decisions.
