1. Question
The Golden Rice variety is rich in which of the following?
CorrectAns;- b) Beta Carotene
Explanation;-
• Golden rice (which helps in Food Fortification Programme of India) is genetically modified in order to produce Beta Carotene, which is not normally produced in rice.
• Beta carotene is converted into Vitamin A when metabolized by the human body.
• We need Vitamin A for healthier skin, immune systems, and vision.
Golden Rice grain compared to white rice grain in screenhouse of Golden Rice plants. Above image of Difference between Normal Rice and Golden Rice.

2. Question
“ELISA Test” sometimes seen in the news is related to ?
CorrectAns;- a) Test that detects and measures antibodies in the blood.
Explanation;-
ELISA (enzyme-linked immunosorbent assay) Antibody Test
• It is a test that detects and measures antibodies in the blood.
• It can be used to determine antibodies related to certain infectious conditions e.g. to diagnose HIV, which causes AIDS, Zika virus etc.
• They have high sensitivity and specificity and are designed specifically for screening large numbers of specimens at a time, making them suitable for use in surveillance and centralized blood transfusion services.
• Recently, National Institute of Virology (NIV) Pune has developed and validated the 1st indigenous IgG ELISA test “COVID KAVACH ELISA” for antibody detection of COVID-19.
• In European countries, this test is being used as an “immunity passport” for people wanting to return to work while being assured that they have immunity against Covid-19.

3. Question
Which of the following are the genetically modified crop’s?
CorrectAns;- d) All of the above
Explanation;-
• In India, the Genetic Engineering Appraisal Committee (GEAC) is the apex body that allows for commercial release of GM crops.
• In 2002, the GEAC had allowed the commercial release of Bt cotton. More than 95% of the country’s cotton area has since then come under Bt cotton.
• All the above mentioned crops in options are Genetically modified crops.
Above image show’s how Genetic Engineering Performed.

4. Question
The first transgenic plant to be produced is?
CorrectAns;- b) Tobacco
Explanation;-
• The first genetically engineered crop plant was tobacco, reported in 1983. It was developed creating a Chimeric gene that joined an antibiotic resistant gene to the T1 plasmid from Agrobacterium.
