Question

Select the four statements that are true.
Both the wild-type and mutant maize leaves have the same morphology.
In wild-type maize plants, the KN1 gene is expressed differentially in shoot apical meristem cells and leaf cells.
In wild-type maize plants, the KN1 gene is present in shoot apical meristem cells, but not in leaf cells.
Leaves of the mutant maize plants produce more KN1 protein than leaves of wild-type maize plants.
In mutant maize leaves, the KN1 gene is mostly not expressed.
Expression of the KN1 gene in shoot apical meristem cells produces a protein involved in the maintenance of shoot apical meristems.
In wild-type maize plants, the KN1 gene is mostly expressed in shoot apical meristem cells.

Explanation / Answer

No. The correct answers are here:


In wild-type maize plants, the KN1 gene is expressed differentially in shoot apical meristem cells and leaf cells. Leaves of the mutant maize plants produce more KN1 protein than leaves of wild-type maize plants. In wild-type maize plants, the KN1 gene is mostly expressed in shoot apical meristem cells. Expression of the KN1 gene in shoot apical meristem cells produces a protein involved in the maintenance of shoot apical meristems.
