Question 1:

Which of the following is a commonly used tool for introducing foreign genes into organisms?

Explanation: Plasmids are commonly used as vectors to introduce foreign genes into organisms during genetic modification.

Question 2:

What is the purpose of the promoter region in a genetic construct?

Explanation: The promoter region is responsible for initiating transcription of the inserted gene, allowing it to be expressed.

Question 3:

Which of the following techniques allows for precise gene editing and modification?

Explanation: CRISPR-Cas9 is a technique that enables precise gene editing and modification by targeting specific DNA sequences.

Question 4:

Which of the following is an example of genetically modified crops?

Explanation: Golden rice is an example of genetically modified crops, as it has been engineered to contain increased levels of vitamin A to address vitamin A deficiency in developing countries.

Question 5:

What is the purpose of selecting transformants in genetic engineering?

Explanation: Selecting transformants allows researchers to identify the presence of the desired genetic modification in order to isolate and study organisms with the desired traits.
