Multiple choice

What is the primary goal of genetic engineering in the context of food security?

  1. To increase crop yield and productivity

  2. To enhance the nutritional value of crops

  3. To reduce the use of pesticides and herbicides

  4. To create crops that are resistant to pests and diseases
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering aims to modify the genetic makeup of crops to improve their yield and productivity, thereby addressing the issue of global hunger.

Multiple choice

Which genetic engineering technique is commonly used to increase crop yield?

  1. Gene silencing

  2. Gene editing

  3. Transgenesis

  4. Genome sequencing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Transgenesis involves transferring genes from one organism to another, allowing the recipient organism to express new traits. This technique is often used to introduce genes that enhance crop yield and productivity.

Multiple choice

What is the role of genetic engineering in developing crops that are resistant to pests and diseases?

  1. It introduces genes that produce natural pesticides

  2. It enhances the plant's immune system

  3. It modifies genes to make crops inedible to pests

  4. It alters genes to attract beneficial insects
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering can introduce genes that enable crops to produce natural pesticides, deterring pests and reducing the need for chemical pesticides.

Multiple choice

How does genetic engineering contribute to enhancing the nutritional value of crops?

  1. By increasing the protein content

  2. By adding essential vitamins and minerals

  3. By reducing the levels of anti-nutrients

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetic engineering can enhance the nutritional value of crops by increasing protein content, adding essential vitamins and minerals, and reducing levels of anti-nutrients that interfere with nutrient absorption.
