**Statement A: Agrobacterium tumefaciens, a pathogen of several dicot plants, is able to deliver a piece of DNA known as ‘T-DNA’ into plant host cells, transforming them.**
Agrobacterium tumefaciens is a gram-negative bacterium that is capable of causing crown gall disease in dicot plants. This bacterium has a unique ability to transfer a piece of its own DNA, known as the T-DNA, into the host plant's cells. This transfer of T-DNA occurs through a process called horizontal gene transfer.
During infection, A. tumefaciens attaches to the host plant's cell surface and forms a structure known as the "T-pilus." This T-pilus is responsible for transferring the T-DNA from the bacterium into the plant cell. The T-DNA is integrated into the plant genome, leading to the transformation of the plant cell.
Once the T-DNA is integrated, it is expressed by the plant cell's own machinery, leading to the formation of tumor-like structures called crown galls. These crown galls provide nutrients and a suitable environment for the growth and survival of A. tumefaciens.
Therefore, statement A is correct.
**Statement B: Non disarmed retroviruses are used to deliver desirable genes into animal cells.**
Retroviruses are a group of RNA viruses that have the ability to convert their RNA genome into DNA and integrate it into the host cell's genome. This unique feature of retroviruses has been exploited for gene delivery purposes.
However, retroviruses are potentially harmful as they can cause diseases in animals. Therefore, the use of non-disarmed retroviruses, which are retroviruses that have not been genetically modified to remove their pathogenic properties, is not a common practice in gene delivery.
Instead, scientists have developed various safe and efficient viral vectors, such as lentiviruses and adenoviruses, for gene delivery into animal cells. These viral vectors are engineered to be replication-defective and non-pathogenic, making them suitable for gene therapy applications.
Therefore, statement B is incorrect.
In conclusion, the correct option is B: Statement A is correct while statement B is incorrect. Agrobacterium tumefaciens is capable of delivering T-DNA into plant host cells, while non-disarmed retroviruses are not commonly used for gene delivery into animal cells.
