Reverse transcriptase is characteristic of retroviruses, including HIV (human immunodeficiency virus), the virus responsible for AIDS (acquired immunodeficiency syndrome). All retroviruses encode a polymerase enzyme in their pol gene that is both necessary and sufficient for the replication of their RNA genomes.
PDO positive phase global pattern. The Pacific Decadal Oscillation (PDO) is a robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin.
The San Andreas Fault is a continental transform fault. It is around eight hundred and ten miles long and forms the boundary between the Pacific and the North American lithosp â¦ heric plates. In California this crack in the crust of the earth is visible.he San Andreas Fault is an example of a transform boundary in which plates slide past each other. This type of fault may also be known as a strike slip fault. During this pla â¦ te motion, lithosphere is neither created nor destroyed.
