Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The following are the examples of transgenic organisms EXCEPT
A
Pseudomonas bacteria strain can breakdown hydrocarbons
B
Sheep that produce milk with human growth hormone
C
Rhizobium bacteria in root nodules that have / the ability to fix nitrogen
D
Plants that are resistant to glyphosate
Explanation: 

Detailed explanation-1: -So the correct option is “Pinus".

Detailed explanation-2: -Rhizobium is a bacterium found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.

Detailed explanation-3: -Examples of this type of nitrogen-fixing bacteria include species of Azotobacter, Bacillus, Clostridium, and Klebsiella.

Detailed explanation-4: -Rhizobium spp. are soil-dwelling -Proteobacteria that can fix nitrogen in a symbiotic relationship with leguminous plants. Nodules develop on the roots of nitrogen-starved legumes such as peas, beans, clover, and soy.
