The genomes of all retroviruses contain the three genes gag, pol and env.

For sustainable expression of a trangene in the successive generation of a cell line in culture, the ideal gene transfer can be obtained using 

 lentiviral vector 

adenoviral vector 

 plasmid DNA containing the transgene

Microbial leaching of copper with the common copper ore CuS, in which copper exists as Cu2+   Acidophillus ferrooxidans oxidizes the sulfide in CuS to SO42, releasing Cu2+.

In uranium leaching, Acidophillus ferrooxidans oxidizes U4+ to U6+ with O2 as an electron acceptor. 

However, Uranium leaching depends more on the abiotic oxidation of U4+  by Fe3+ with A. ferrooxidans contributing to the process mainly through the reoxidation of Fe2+ to Fe+3, as in copper leaching.
