The transformation of a plant cell is successful if Question 9 options: a. the plasmid that entered the cell reproduces inside the cell. b. the foreign DNA is integrated into one of the cell's chromosomes. c. the cell reproduces. d. a plasmid has entered the cell.

b. the foreign DNA is integrated into one of the cell's chromosomes.

Explanation:

The transformation of a cell is generally considered to be successful if the foreign DNA is integrated into one of the chromosomes of the cell.

Gene or genetic transformation is a process during which a foreign gene (DNA) is introduced into the genome of a host organism using a vector DNA.

The vector DNA is first infused with the gene of particular interest in order to make a recombinant DNA. The recombinant DNA is then introduced into the cell that is to be transformed.

Successful transformation will see the gene of particular interest (the foreign DNA) integrated into one of the chromosome of the cell.

The correct option is b.

b. the foreign DNA is integrated into one of the cell's chromosomes

Explanation:

Transformation involves following steps:

The plasmid is removed from the bacterium, and the T-DNA is cut by a restriction enzyme. Foreign DNA is cut by the same enzyme. The foreign DNA is inserted into the T-DNA of the plasmid. The plasmid is reinserted into a bacterium The bacterium is used to insert the T-DNA carring the foreing gene into the chromosome of a plant cell. The plant cells are grown into culture. A plant is generated from a cell clone. Al of its cells carry the foreign gene and may express it as a new trait. The transformation of a plant cell is successful if the foreign DNA is integrated into one of the cell's chromosomes.
