Knowing the genome size of E. coli and the fact that it can divide ca. every 20 minutes (under optimal growth conditions), calculate the rate of DNA replication in bp/sec (assume only one origin of replication and bidirectional replication). use 4.385 x 10^-9 as the weight in micrograms for the genome size

Escherichia coli is a red-pigmented organism. True O False The results of the MR-VP test can be directly read from the test without the addition of any other chemicals. True False
Salmonella, Shigella and Escherichia coli are important pathogens of the gastrointestinal tract. Provide a detailed description of these pathogens, including diagnostic methods used, their role in asymptomatic carriage and disease, pathogenesis, treatment, and potential complications that may occur in other organs of the body following on from gastrointestinal infection.

what results would you get when testing these organisms (Klebsiella pneumoniae, Escherichia coli, Staphylococcus saprophyticus, Proteus mirabilis, Proteus vulgaris, Providencia stuarti, Pseudomonas aeruginosa, Enterobacter aerogenes, Morganella morganii) Tests being run: MacConkey agar test, a Gram staining test, SIM agar and Urea agar (just indicate if results are negative or positive)
Choose the true statement about housekeeping genes in Escherichia coli. Housekeeping genes are constitutively expressed. A housekeeping gene's expression should stop when the cell is placed in a different environment. Most of E. coli's genome encodes housekeeping genes. Examples of housekeeping genes in E. coli include antibiotic resistance genes and lactose catabolism genes. Choose the frameshift mutation that is the riskiest for a prokaryotic cell. A deletion of three DNA nucleotides from the DNA template strand A deletion of one...
"Three organisms were innoculated on a culture media. Results showed Escherichia coli as red colonies, no growth of Staphylococcus epidermidis, and colorless colonies of Salmonella enterica. The medium is:" a selective and differential b differential c selective d minimal e heterotrophic "A bacterium was incubated with aeration in a nutrient medium containing two carbon sources. After logarithmic growth, a lag phase was observed for 25 minutes. Then logarithmic growth at a slower rate was observed. Which substate was preferred by...

Based on the bacteria, please fill out the table with the true
results under each circumstance. Also, tell why each ingredient is
added to the bacteria and what is the purpose of it? what does it
do to bacteria?
