Question

Bt crops, including potatoes and cotton, are genetically engineered using laboratory techniques. Which of the following utilizes recombinant DNA technology to produce advantageous traits in the crops that are produced?
A. Genetically engineered crops have natural characteristics that give them a genetic advantage.
B. Genetically engineered crops have a genetic advantage because the parent strains have advantageous traits.
C. Genetically engineered crops have an advantageous gene from another organism inserted into their genome.
D. Genetically engineered crops naturally produce larger plants and bountiful products.

Answer 1

The correct answer is (c).

Explanation:

• Bt crops are the crops which are genetically engineered.

• They produce the toxin which is similar to Bt so crop is protected from the pests.

• As Bt crops are widely used, some pests show Bt resistance.
• Recombinant DNA technology or RDT is the technique which is used for joining molecules of DNA that belongs to two different species.
• A new genetic combination is seen when the recombinant DNA molecule is inserted into a host organism.
• Hence, the genetically engineered crops have an advantageous gene from another organism inserted into their genome.
