Predict the most likely outcome of culturing transformed e coli in the presence of tetracycline answer

Llana [10]3 years ago

E. coli are a species of bacteria. Like all bacteria, they have a round piece of DNA that contains most of their genetic information, but also plasmids, that contain some more. Plasmid can be passed on from bacterium to bacterium and they contain information for fighting antibiotics. Tetracycline is such an antibiotic. The process of putting a plasmid inside a bacterium is called transformation. So what the above sentence really says, is that a bacterium just got a plasmid that is probably holding the genetic information to produce proteins that fight antibiotics like tetracycline. While regular strains of E. coli might not be able to deal with tetracycline, transformed strains will probably be able to survive it. Hence, the culture will have live bacteria and the bacteria that have a plasmid against tetracycline will be favored and survive.

Alex_Xolod [135]

Explanation:

Photosynthesis is a process taking place in the green plants which are involved in the formation of the glucose molecule using Carbon dioxide and water in the presence of sunlight.

The process of photosynthesis takes place in two phases:

1. Light-dependent phase

2. Light independent phase

<u>Light-dependent phase </u>

Light-dependent phase takes place in the thylakoid membrane where the Photosystem I and II are present.

The photosystem II absorbs the sunlight of 680 nm wavelength which excites the electron of the chlorophyll. The electron moves in the photosystem and through the reaction center-exit the photosystem and enters the electron transport chain.

The electron is then transferred via the electron carriers like plastoquinone, cytochrome, and plastocyanin and is transferred to photosystem I which absorbs the light at 700 nm. From here the electron is taken by ferrodoxin and form NADH.

The electron then reaches the ATP synthase and forms the ATP molecules thus ATP and NADPH are formed in the reaction but the loss of electron in chlorophyll is fulfilled by the water molecule which on hydrolysis provides the electrons and stabilize the structure.

<u>  Light independent phase </u>

The phase during which the Rubisco enzyme binds with the carbon dioxide and forms 3-PGA. This 3 PGA is then reduced to G3P which requires the 6 ATP molecules. The G3P molecule then forms 1 molecule of glucose and the Rubp is again regenerated.

KengaRu [80]
Phat1 = 9/142
Phat 2 = 5/268
Phat 3 14/410
Test statistics = (Phat 1 - Phat 2) / (Square root of (phat × (1- phat))
times the square root of (1/n1 + 1/n2))
Test statistics = 2.373
P- value = 2× (1- normal cdf (2.373, 0, 1)) 
= 0.0176
At the level of significance, there is difference between the proportion of drug-resistant wihtin the two states.
