Other protists include pathogenic species such as the kinetoplastid Trypanosoma brucei, which causes sleeping sickness and species of the apicomplexan Plasmodium which cause malaria.ost eukaryotic algae are autotrophic, but the pigments were lost in some groups. Other protists are heterotrophic, and may present phagotrophy, osmotrophy, saprotrophy or parasitism. Some are mixotrophic. Many protists are flagellate, for example, and filter feeding can take place where the flagella find prey.
The Las Vegas Arena is a joint venture between MGM Resorts International and AEG, both long-standing partners of PBR. MGM Grand Garden Arena was home of the first PBR Series World Finals in 1994 and hosted the event through 1998 before PBR moved to the Thomas & Mack Center, a larger venue at UNLV, in 1999.
pBR322 is a plasmid and was one of the first widely used E. coli cloning vectors.Created in 1977 in the laboratory of Herbert Boyer at the University of California, San Francisco, it was named after the postdoctoral researchers who constructed it.The p stands for plasmid, and BR for Bolivar and Rodriguez..he plasmid has unique restriction sites for more than forty restriction enzymes. 11 of these 40 sites lie within the tetR gene. There are 2 sites for restriction enzymes HindIII and ClaI within the promoter of the tetR gene. There are 6 key restriction sites inside the ampR gene.
