Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetic engineering for disease resistance raises ethical considerations related to the potential environmental impact, unintended consequences of genetic modifications, and long-term effects on human health, requiring careful assessment and regulation.

Multiple choice

What is the term used to describe the process of introducing genes from one species into another species?

  1. Transgenesis

  2. Cisgenesis

  3. Gene editing

  4. Genome editing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Transgenesis refers to the process of introducing genes from one species into the genome of another species, allowing the recipient organism to express and potentially benefit from the introduced genes.

Multiple choice

What is the term used to describe the process of modifying an organism's own genes without introducing foreign genes?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cisgenesis involves modifying an organism's own genes, typically by introducing genetic variations or regulatory elements, without introducing foreign genes from other species.
