In Order for the Dissociation Element (Ds)mutations in Corn to Be

Question

In order for the dissociation element (Ds)mutations in corn to be stable,
A)an Ac element must be present.
B)an Ac element must not be present.
C)the Ds must contain the gene for transposition.
D)the DNA must not be replicated.
E)None of these

Accepted Answer

The presence of an Ac element can cause the instability of the Ds mutations in corn, while the absence of an Ac element can help maintain stability. Therefore, option B is the correct choice. Options C and D are incorrect as they are not related to the stability of Ds mutations. Option A is incorrect as it suggests that the presence of Ac element is necessary for stability, which is not true.
