Biology Bacteria are believed to be on the list of oldest cells on Earth, fossils show bacteria-like organisms were around almost 3. They are unicellular micro-organisms that lack a membrane bound nucleus and contain no organelles.

Many people consider these to be the reason for many diseases, that they are, but the human body includes trillions of bacteria, aiding techniques such as digestion and development.

Mitochondria on the other hands are organelles within the majority of eukaryotic skin cells, they produce energy by means of adenosine triphosphate ATP.

What could these organelles found in Edible vaccines research papers have as a common factor with bacteria, that happen to be prokaryotes? Maybe this essay will treat that question and try to answer it. To do this in the first section of this essay I am going to consider the structural similarities between them both.

I am going to then continue to compare the practical similarities in the next section of this essay which will then be followed by a section outlining and detailing the endosymbiotic theory that ought to help to clarify the previous sections.

Finally I will summarise the similarities between mitochondria and bacterias and the causes of these similarities and the validity of the idea detailing them. Structure At first glimpse bacteria and mitochondria look to employ a different internal composition and can likewise have a radically different exterior condition, but inside they certainly reveal some similarities.

The internal structure of bacterias is simple, it includes no membrane destined organelles, but instead it includes a nucleoid which is the central part of the cell and it is where the DNA is generally restricted to.

Ribosomes are present in the cytoplasm of the bacteria as well as safe-keeping granules. All bacterias have a plasma membrane, most Edible vaccines research papers have a cell wall membrane even though some have a capsule, others do not 1.

Some bacteria likewise have flagella that happen to be tiny whip-like set ups often located at one end of the cell. Mitochondria are positioned in the cytoplasm of both pet and plant skin cells; these are cylindrical structures that contain an outer membrane, internal membrane and matrix.

Like bacteria, mitochondria likewise have their own round DNA genome which is distinct from the nucleus of the cell which is positioned in the matrix. The membrane of the mitochondria is also very similar to the membrane found round the bacteria; it is double layered and is composed from lipids, just like a prokaryotes membrane.

That is interesting as it shows no similarities with a eukaryotic cell's cytoplasm, but instead it's very similar to the composition of the bacterial membrane. The inner folds of the mitochondrial membrane, cristae, are incredibly much like mesosomes within bacteria. Mitochondria also contain ribosomes a lot like those within bacterias; this will be described further within the next section.

Function The main function of bacterias, like any organism, is to replicate, and while mitochondria's main function is to create energy by means of ATP it also needs to reproduce. Mitochondria are created by an activity very similar to binary fission, the technique by which bacterias divide.

Whenever a bacterium gets to a certain size, it splits down the middle to produce two organisms. Inside a mitochondrion the nucleus signs the cell to create more organelles, but only the mitochondria actually replicate themselves while other organelles have to be comprised from substances present within the cell.

There is an electron transport chain found in both the plasma membrane around a prokaryote as well as in the membrane surrounding the mitochondria but it is absent in membrane of eukaryotic skin cells. Proteins are needed in a cell to perform all functions and everything synthesis of the proteins takes place in ribosome; these ribosomes are present throughout the cell but mitochondria have their own ribosomes to produce the proteins they need.

Chemical and microscopic research shows how the structures of mitochondrial and bacterial ribosomes show more similarities with the other person than with ribosomes in eukaryotic cells. Ribosomes found in the cytoplasm of eukaryotic cells are 80S in proportions while ribosomes found in bacterias and mitochondria are 70S in proportions 3.

One experiment carried out by Margulis proved that the protein synthesis of both mitochondria and bacterias are hypersensitive to erythromycin and chloramphenicol and insensitive to cyclohexamide and emetine whilst cytoribosomal proteins synthesis is insensitive to erythromycin and chloramphenicol and is also usually delicate to cyclohexamide and emetine, recommending that mitochondrial ribosomes will vary from those found in the cytoplasm of eukaryotic skin cells, and act like those found in bacteria.

This experiment among other structural and functional similarities lead to Margulis to formulate the idea of endosymbiosis. Endosymbiosis The theory of endosymbiosis have been around before the evidence released by Lynn Margulis, but it was her work that made it a widely accepted theory among biologists.

Included in her hypothesis was the idea that mitochondria are the result of endocytosis of aerobic bacteria. This would make clear the similarities between mitochondria and bacteria, and why mitochondria change from what would be expected from an average eukaryotic organelle.

The theory purposes that a proto-eukaryotic cell ingested an aerobic bacterium but it failed to digest it. The aerobic cell then thrived due to the cell's cytoplasm being full of partially digested food molecules, and some of the ATP may have leaked in to the cell's cytoplasm.

This occurred around a period where the focus of oxygen in the atmosphere was increasing and aerobic respiration was beneficial to survive 3.

An increase in ATP will need to have caused a growth benefit to the proto-eukaryote, allowing it to dominate over other cells that lacked cell surfaces and endosymbionts. The endosymbiont, originally the aerobic bacterium, eventually became dependent on the coordinator for both cover and nutrients, signifying there is little need for genes involved with these processes.

On the other hand, due to the endosymbiont only being permitted to remain if it prolonged to capture and store energy, there was a strong selective pressure to retain the genes involved with energy take and storage area. Eventually genes whose products were useless to the web host eroded and were ultimately lost.

Finally as the genome lowering sustained, the endosymbiont developed into an energy-providing organelle. However, even more recent research shows that the endosymbiont may have been an anaerobic bacterium with a fermentative metabolism 4.A Review on Impacts of Genetically Modified Food on Human Health Charu Verma1, Surabhi Nanda2, R.K.

The use of gene Researchers are working to develop edible vaccines in tomatoes and potatoes [19, 20]. These vaccines. Edible vaccines hold great promise as a cost-effective, easy-to-administer, easy-to-store, fail-safe and socioculturally readily acceptable vaccine delivery system, especially for the poor developing regardbouddhiste.com: Pratibha Chaturvedi, Abhay Chowdhary.

Creating edible vaccines involves introduction of selected desired genes into plants and then inducing these altered plants to manufacture the encoded proteins. This process is known as " transformation," and the altered plants are called " transgenic plants.".

Research on our plant-made vaccines and mAbs for biodefence has continued as collaborative programmes between Mapp and ASU, gradually involving a wider range of multidisciplinary participants. Edible Vaccines Scientific American September 67 P HO T OGR AP HS BY FOREST M C MULLIN BANANA TREES AND TOMATO PLANTS growing at the Boyce Thompson Institute for Plant Research at Cornell Uni-versity have been genetically engineer ed to produce vaccines in their fruit.

Bananas are particularly appealing as vaccines . Immunology textbooks currently report orally administered antigens as inducing immune tolerance rather than immune stimulation. Nevertheless, current plant-based edible vaccine technology, if sufficiently developed, may offer several advantages.

For example, it is easy to apply, store, and transport.
