E Coli Infections

No, E. coli does not use photosynthesis as it is a bacterium that lacks the organelles necessary for this process, such as chloroplasts. Instead, E. coli obtains energy through other metabolic processes like fermentation or aerobic respiration.

binding to the trp repressor, causing a conformational change that allows it to bind to the operator region of the trp operon. This blocks RNA polymerase from transcribing the genes, turning off expression of the trp operon.

My answer is 3, I am pretty sure I am right, but I would double check to make sure. I am in ninth grade taking biology at PineTree.

Yes, E. coli has a cell wall. It is composed of peptidoglycan, a unique structural component found in most bacterial cell walls. The cell wall provides structural support and protection for the bacterium.

The positive control of the lactose operon in bacteria involves the binding of the catabolite activator protein (CAP) to the CAP site upstream of the promoter, enhancing RNA polymerase binding and increasing transcription of the operon in the presence of glucose limitation. This allows the bacteria to effectively utilize lactose as an alternative carbon source when glucose is scarce.

T4 bacteriophage is a common virus that infects E. coli bacteria. It injects its genetic material into the bacterium, taking over the host's machinery to replicate itself. This ultimately leads to the destruction of the bacterial cell and the release of new phages.

No, BL21(DE3) E. coli is a non-pathogenic strain commonly used in research labs for protein expression. It is derived from E. coli strain B and has been engineered to have a deletion in the gene coding for the protease Lon, making it more suitable for protein production.

E. coli is a bacteriabelongs to gram negative group. It is a opportunistic pathogen i.e., it will reside as a normal flora inside ur body, when your immune system get weakend it wud become a pathogen and cause diseases. eg., Diarrhoea.

The E. coli bacteria eat undigested nutrients in mammal large intestines. It resides in these intestines. They are essential to healthy digestion, but sometimes cause intestinal gas.

Some strains do not know when to stop and will eat the lining of those intestines too! These can cause bloody diarrhea and fatal infections!

if a regulatory protein in its active state turns off the expression of the operon, the operon is said to be negatively regulated by the regulatory protein. if the regulatory protein in its active state truns on the operon, the operon is positively regulated by the regulatory protein. an operon regulated by a repressor is therefore negatively regulated, because the presence of the active repressor prevents transcription of that operon. in contrast, an operon regulated by an activator is positively regulated, because in its active state the activator protein turns on transcription of the operon under its control. the lac operon of E. coli repressor(lac repressor) is synthesized through the activity of the gene lac I, known as regulator gene. the active form of the lac repressor, is a tetramer that contains four copies of the gene I product. in the absence of the inducer, the repressor binds to the lac operator sequence, preventing RNA polymerase from binding to the promoter and transcribing the structural genes. thus the lac operon is negatively regulated associated with the lac operon, there is another site, 16 base pairs upstream of the promoter, which is used for a positive control of the gene expression. this site is called catabolic activator protein site or cyclic AMP(cAMP) protein site or catabolite gene activator(cga) site, because it is utilized for binding of CAP or cga to stimulate gene expression. CAP can bind to this site only when it is bound with cAMP. by binding to it, the CAP-cAMP complex exerts a positive control over the transcription process. it has an effect exactly opposite to that of repressor binding to an operator. yhe effector molecule cAMP determines the effect of CAP on lac operon transcription. presence of glucose inhibits the formation of cAMP and prevents it to bind to CAP

according to the packaging on Baytril, it should not be given during the rapid growth period so for small dogs it should not be given till after 8 mos and giant breeds, not till after 18 mos. It can cause cartilage deterioration.

It will if cooked to the proper temperature. Just cooking it 'al dente' will not be sufficient to remove the bacteria. Be certain to store it properly after being cooked.

Also, bringing the food to a high enough temperature to kill the E. coli SLOWLY will make the E. coli actually grow stronger and more able to resist the heat. So it is important to bring it to the high temperature quickly.

You should boil raw beef or chicken for a minimum of one (1) hour at 100 degrees Celsius/212 degrees Fahrenheit (at sea level) to be safe. At higher altitudes (>3500 feet or >1km above sea level) you will need to boil it longer as water boils at lower temperatures at high altitudes.

Do NOT recook or reheat meat left out at room temperature for 2 hours or longer. Throw it away.

A better way to phrase the question you are asking is "Can PEA agar grow E. coli?"

The answer is yes, but only a small amount of growth will be observed because PEA is partially inhibitory to Gram negative organisms and E. coli is Gram negative.

A bacteria called Escherichia coli. It is usually abbrieviated to E. coli

What is the bacteria called "C-Diss?

ribosomes.

The answer is no, and as for references, please visit the related link below. It's the top line.

E.Coli feeds on undigested nutrients in mammal intestines.

E. coli does not turn into anything. What it does is multiply. And depending on the strain that can be either beneficial or harmful.

Yes

Salmonella enterica

E. coli lives in the intestines and is adapted for living there. The average body temperature is 37 degrees Celsius

No
