Question 1

Some bacterial transposons, known as Tn elements, are larger than insertion sequences (IS elements) and contain protein-coding genes that have human health significance. What might such a bacterial transposon contain?
◦ pseudogene
◦ dissociation element
◦ proto-oncogene
◦ drug resistance
◦ oncogene

Question 2

Barbara McClintock discovered mobile elements in corn by analyzing the genetic behavior of two elements, Ds and Ac. The interplay between these two elements has become one of the most interesting stories of discovery in the field of genetics. How do Ds and Ac interact?
Ds moves only if Ac is present in the genome; Ac is capable of autonomous movement.
◦ The movement of Ac is dependent on two forms of Ds.
◦ Both elements can move only within chromosome 9.
Ds causes a deletion next to the insertion site of Ac.
Ac causes a deletion next to the insertion site of Ds.
