Ds (Dissociation) elements in maize are indeed structurally heterogeneous, indicating that they vary in their structure. Some Ds elements have been shown to derive from Ac (Activator) elements through the loss of internal sequences, which supports the idea of their evolutionary relationship. Additionally, both Ds and Ac elements possess the same inverted terminal repeats, a characteristic feature that facilitates their transposition mechanism. Therefore, all the statements provided are true regarding Ds elements in maize.
