Transgenic plants are
Options
- Aproduced by a somatic embryo in artificial medium
- Bgenerated by introducing foreign DNA in to a cell and regenerating a plant from that cell
- Cproduced after protoplast fusion in artificial medium
- Dgrown in artificial medium after hybridization in the field
Correct answer
B. generated by introducing foreign DNA in to a cell and regenerating a plant from that cell
Step-by-step solution
The plants obtained through genetic engineering contain a gene or genes usually from an unrelated organism, such genes are called transgenes and the plants containing transgenes are known as transgenic plants. These plants are often called as genetically modified or GM crops, eg, Flavr saur tomatoes, golden rice. Plants are made transgenic for identification, expressing the gene activity in time, to produce several chemicals like fatty acids, sugars, cellulose, rubber, etc.
