Which of these is NOT true. Once the Human Genome was completely mapped, scientists found
that:
a) Each specific gene has a fixed location on a particular chromosome
b) If you know where on a chromosome a gene is located, then that tells you exactly what gene it is
c) There seem to be locations on the chromosomes where the genes don't connect to any traits. We
call these "Junk DNA" or "Non-coding DNA
d) Genes move around on the chromosomes and could be located anywhere

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.
