Which of the following is NOT true regarding the differences between a genomic and cDNA library? Select one: a. A genomic library is prepared from total genomic DNA, whereas a cDNA library is prepared from mRNA. b. Genomic libraries contain much more sequence information and are much larger than cDNA libraries. c. Genomic libraries contain coding and noncoding (regulatory, intron, etc.) sequences, whereas cDNA libraries contain only coding sequences along with their associated 5? and 3? untranslated regions. d. cDNA libraries are generated with the use of reverse transcriptase, whereas genomic libraries are not. e. Genomic libraries contain fewer restriction enzyme sites, whereas cDNA libraries contain many morE.

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.
