Which is a product of genetic engineering related to weed control?
A
Roundup-ready soybeans
B
High-oleic peanuts
C
Bt corn
D
Delayed-ripening tomatoes
Explanation: 

Detailed explanation-1: -Monsanto ‘s Roundup Ready soya has been genetically engineered (GE) to make the soya tolerant to the herbicide glyphosate, which is also manufactured by Monsanto and sold as Roundup. GE Roundup Ready soybean was one of the first GE crops ever grown commercially.

Detailed explanation-2: -The CP4 EPSPS gene was cloned and inserted into soybeans. The CP4 EPSPS gene was engineered for plant expression by fusing the 5’ end of the gene to a chloroplast transit peptide derived from the petunia EPSPS.

Detailed explanation-3: -Roundup Ready crops are crops genetically modified to be resistant to the herbicide Roundup. Roundup is the brand-name of a herbicide produced by Monsanto. Its active ingredient glyphosate was patented in the 1970s. Roundup is widely used by both people in their backyards and farmers in their fields.

Detailed explanation-4: -The multinational, agricultural biotechnology corporation Monsanto developed the first widely used genetically modified crop in 1996 with the introduction of the “Roundup Ready” soybean.

Detailed explanation-5: -They are also known as “glyphosate tolerant” soybeans. RR Soybeans were first planted commercially in 1996. When planting RR soybeans, a farmer can spray the entire crop with glyphosate, killing only the weeds and leaving the soybeans alive.
