Genetically modified grass varieties that carry genes for disease and drought resistance are now available. they were produced by recombinant dna technology. however, the government has still not approved the sale of most of them, due to cautionary factors. what is the main reason for this concern?

a) the possibility of the fragile recombinant organisms dying.
b) the possible patent violations from competing biotechnology companies.
c) because the new genetically altered grasses are too expensive for consumers.
d) release of genetically engineered organisms into the environment with unpredictable results.

The correct answer is option-D Release of genetically engineered organisms into the environment with unpredictable results.  

Genetically modified crops and plants contain desirable genes such as high growth rate, nutrient retention property, protection against pests and many more but we are yet to conclude if these genetic modified crops have good long lasting effects on people.

The health benefits of these crops are yet to be studied which is why not all of them are approved for human use.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.
