Answer: Option D. -> all of these
:
D
In 1997 the first transgenic cow Rosie produced human protein-enriched milk (2.4 grams per litre). The milk contained the human protein alpha-lactalbumin and was nutritionally a more balanced product for consumption by human babies than natural cow-milk.

Answer: Option A. -> True
:
A
Cloning is the process of producing similar populations of genetically identical individuals. This occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Therefore, genetically, clones are exact copies of each other.

Answer: Option B. -> Phytohormone coding genes
:
B
Wild Ti plasmid is a large plasmid which contains 200 to 800 kilobases. This plasmid contains genes coding for phytohormones such as auxins, cytokinins and opines. Increased production of phytohormones induces uncontrolled growth of cells leading to tumor formation.

Answer: Option D. -> SCID
:
D
The first clinical gene therapy was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) deficiency which results in SCID. This enzyme is crucial for the immune system to function. The disorder is caused due to the deletion of the gene for adenosine deaminase

D
Biopiracy is a common terminology that deals with theft of ideas or inventions in the field of biology. Broadly speaking, biopiracy includes the following - Unauthorized extraction of biological resources, Patenting without compensation, and Spurious ‘inventions’

Answer: Option C. -> Ralstonia eutropha
:
C
Developed by Daniel G. Nocera and his team, Ralstonia eutropha is a bacterium that can absorb hydrogen and carbon dioxide from the atmosphere and convert it into alcohol fuel in the presence of sunlight

Answer: Option D. -> Tomato
:
D
The first commercially grown, genetically modified crop approved for human consumption and sale in the U.S., in 1994, was the Flavr Savr tomato. It had a longer shelf life, because it took longer to soften after ripening, while still allowing the tomato to retain its natural colour and flavour. The tomato was made more resistant to rotting by adding an antisense gene which interferes with the production of the enzyme polygalacturonase. It was produced by a Californian company Calgene that unfortunately did not make make a profit from Flavr Savr and hence stopped selling it in 1997.

Answer: Option D. -> insects
:
D
Bt brinjal is a transgenic plant with insect resistance. It contains the Bt gene that encodes the Bt toxin derived from Bacillus thuringiensis. The GM crop has been used to combat the widespread problem of crop loss due to insect pests consuming the plants.

The Cry gene was isolated from the bacteriumBacillus thuringiensisand was transferred to cotton plant to make it disease resistant. Cry protein expressed in Bt-cotton is toxic to bollworms - a major pest of cotton.
