Plzzz help fast pl fast What is the most efficient procedure that scientists can use to obtain more recombinant DNA for a particular trait? isolate more recombinant DNA
use electrophoresis to separate more recombinant DNA
clone the recombinant DNA in a biological vector
use restriction enzymes to cut the recombinant DNA into fragments

Salmonella typhimurium is a food-borne bacterial pathogen that can cause severe gastrointestinal disease. salmonella is often phagocytosed by macrophages that normally destroy bacterial pathogens, but this bacterium is somehow able to prevent the complete maturation of phagolysosomes. salmonella is able to tolerate the low ph of phagolysosomes, and in fact responds to the drop in ph by secreting toxins that interfere with other cellular responses. which of the following differences would you expect to contribute to the survival of a bacterium within an salmonella-containing phagosome, compared to a healthy phagolysosome? decreased activity of acid hydrolases increased activity of acid hydrolases decreased import of h+ ions increased import of h+ ions my guess is decreased activity of acid hydrolases but i'm not sure.

How do all types of diffusion/passive transport actually ‘work’ without using even the smallest amount of cellular energy?
