The average amino acid length of proteins in Escherichia coli is 235. Therefore, according to the video, the elongation time for an average E. coli protein would be about seconds. How is the small ribosomal unit positioned to allow for translation to start at the proper start codon?Choose one:
A. Shine-Dalgarno sequence
B. The start codon sequence is specifically attracted to the P site.
C. Initiation factors position the mRNA accordingly.
D. The small ribosomal subunit starts at the far 5' end of mRNA where the start codon is located.

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.
