Question 22

(Multiple Choice)

In plants, transposons are often the cause of variegation (the formation of white stripes of cells on a green leaf). Which of the following explains why a transposon might have this effect?


A)The white cells are dead cells. When a transposon moves from one chromosome to another, it kills its host cell.
B)When a bacterium infects a plant cell, the plant cell begins producing bacterial proteins rather than plant proteins.
C)When a transposon "jumps" into the gene involved in the production of the green pigment in a plant, the gene no longer functions so the cells are all white.
D)When a transposon enters a cell, it inhibits the translation of all proteins.
