Question 1:

Which of the following is an example of a genetically engineered organism used in agriculture?

Explanation: Bt cotton is an example of a genetically engineered organism used in agriculture. It is engineered to produce a toxin from the bacterium Bacillus thuringiensis, which helps protect the cotton plant against certain pests.

Question 2:

What is the primary application of recombinant DNA technology in medicine?

Explanation: The primary application of recombinant DNA technology in medicine is gene therapy, which involves introducing or modifying genes in an individual's cells to treat or prevent diseases.

Question 3:

Which technique is commonly used to produce large quantities of a specific protein of interest?

Explanation: Recombinant DNA technology is commonly used to produce large quantities of a specific protein of interest by inserting the gene encoding the protein into a suitable host organism, such as bacteria or yeast.

Question 4:

Which of the following is an application of genetic engineering in environmental biotechnology?

Explanation: An application of genetic engineering in environmental biotechnology is bioremediation, which involves using genetically engineered microorganisms to degrade or remove pollutants from the environment.

Question 5:

Which technique is commonly used to determine the presence or absence of a specific DNA sequence in a sample?

Explanation: Polymerase chain reaction (PCR) is commonly used to determine the presence or absence of a specific DNA sequence in a sample by amplifying the target DNA region of interest.
