Using the information above, digest the DNA samples from person 1 and person 2 using EcoRI on the following pages. Scan the strand for the restriction site and draw an arrow any place this
enzyme would make a cut. Beneath each strand, indicate the number of fragments that would be
created and also the size of each fragment. The size of the fragment is determined by counting
the number of bases pairs on the top strand of each fragment and is recorded in base pairs.
Some of the pieces will have bases overhanging the edge (sticky ends). For example, for a piece
that looks like the fragment below, it would be listed as 9 base pairs (9bp)

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.
