Genetically Altering Mosquitoes to Reduce the Spread of Dengue Fever

The video explores the use of CRISPR technology to genetically modify mosquitoes to combat dengue in Singapore. By altering mosquito genes, scientists aim to reduce the population of dengue-spreading mosquitoes. The video also discusses potential risks, such as gene transfer to other species and ecosystem impacts. Additionally, it touches on genetic modifications in plants to enhance growth and stress reduction.

What is the primary purpose of using CRISPR technology on mosquitoes in Singapore?

• To create a new species of mosquitoes

• To increase the mosquito population

• To identify and differentiate genetically modified mosquitoes

• To make mosquitoes glow for aesthetic purposes

How does the CRISPR CAS 9 technology help in controlling the spread of dengue?

• By making mosquitoes resistant to insecticides

• By increasing the lifespan of mosquitoes

• By ensuring mosquitoes only produce male offspring

• By making mosquitoes immune to dengue

What is a potential risk of using genetically modified mosquitoes?

• They might become resistant to CRISPR technology

• They could spread to other countries

• They could become larger and more aggressive

• Their genes might transfer to other species

What is a concern regarding the impact of eliminating a mosquito species on the ecosystem?

• It could lead to an increase in other insect populations

• It might cause a permanent imbalance in the ecosystem

• It might lead to a shortage of food for mosquito predators

• It could result in a decrease in plant pollination

What other applications of genetic modification are mentioned in the video?

• Developing new types of flowers

• Creating new animal species

• Enhancing human physical abilities

• Improving the nutritional value of vegetables
