Liquid nitrogen is used in agrobacterium transformation to create small, transient pores in plant cells through a process called cryoporation. These pores allow the agrobacterium to deliver DNA to the plant cell more efficiently, increasing the success rate of genetic transformation. Liquid nitrogen also helps in maintaining a low temperature environment, which is necessary for cell survival during the transformation process.
What else can I help you with?
Is liquid nitrogen flamable?
no. In some situations nitrogen is used to put out fires.
Why is liquid nitrogen used in beer cans over liquid oxygen?
The answer is, liquid nitrogen ISN'T used in beer cans. Nitrogen GAS is. And the reason nitrogen gas is used in beer cans is to emulate draft beer such as one would get out of a keg(as opposed to cask) beer.
Is liquid nitrogen legal in Florida?
Liquid nitrogen is used in a wide variety of applications. In particular, it's used in superconducting magnets, which means that Florida would be an incredibly stupid place to locate the National High Magnetic Field Laboratory if liquid nitrogen were illegal there. Want to guess where the National High Magnetic Field Laboratory is? Yes, liquid nitrogen is legal in Florida.
Can liquid nitrogen be used as a fertilizer for agriculture?
No. Firstly liquid nitrogen has a boiling point of 77K. That's -196degrees Celsius, which will freeze all water in contact with it. Not only will the roots not be able to take up water from the soil, water within the plant cells will also freeze, damaging the roots. Secondly, liquid nitrogen will vaporize rapidly when exposed to the environment, which is at room temperature. This means that when liquid nitrogen is poured into the soil, it is not different from the plant absorbing nitrogen in the form of gaseous nitrogen. Thirdly, nitrogen uptake is best facilitated in the aqueous form, ie. dissolved in water in the form of nitrate or ammonium ions. Liquid nitrogen/gaseous nitrogen do not dissolve very well in water.
What is nitrogen condensation?
Nitrogen condensation refers to the process where gaseous nitrogen is cooled and converted into liquid nitrogen at a temperature of -196 degrees Celsius. This liquid form of nitrogen is often used in various industries for cryogenic applications, such as in medical, food, and semiconductor industries.
Why gene gun use in rice transformation?
It's a tool to insert foregin gene into target cells and can be used for any suitable crop or cells for transformation purpose. Now a days, agrobacterium mediated transformation techniques are becoming popular.
How can genetic engineering be used to make a transgenic tobacco plant that glows in the dark?
Agrobacterium-mediated transformation using a plasmid containing a gene for GFP
What method is preferred to generate transgenic plants?
Since transgenic plants contains foreign gene of desired function of other organisms.So the technique of rDna technology is used.Then the rDNA is cultured in the lab then after the formation of small plant it is grown in the outside entertainment.in this way a transgenic plant is produced.
Species of economically important bacteria?
The genera Rhizobium, Bradyrhizobium and Agrobacterium are economically important soil bacteria; Rhizobium and Bradyrhizobium fix nitrogen in symbiosis with the family Leguminosae, and Agrobacterium,besides causing plant diseases, is used as a vector system for introduction of foreign DNA into dicotyledonous plants
Is liquid nitrogen flamable?
no. In some situations nitrogen is used to put out fires.
Can nitrogen used as a fuel in cars?
Yes , it can be. A living example is a Liquid Nitrogen Vehicle.A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary engine. Vehicles propelled by liquid nitrogen have been demonstrated, but are not used commercially.
Can liquid nitrogen gas be condensed?
Yes, liquid nitrogen gas can be condensed to form liquid nitrogen. This is done by lowering the temperature of the gas to its boiling point (-196°C) or below, causing it to condense into a liquid state. Liquid nitrogen is commonly used in various applications such as cryogenic freezing and cooling.
Is liquid nitrogen used in refrigerators for cooling?
No. Refrigerators use a substance called Freon that can readily change from liquid to gas to liquid, moving heat from inside the fridge to the outside. Liquid nitrogen is FAR too cold, and requires too much energy to make the change from gas to liquid.Yes, liquid nitrogen is used in refrigerators. Nitrogen is a diatomic gas. The two nitrogen atoms are bond with a triple bond.
Can there be liquid nitrogen?
Yes, liquid nitrogen exists. It is sold in strong, insulated containers and is used to instantly freeze biological specimens or tissue.
Can liquid nitrogen be used for cooling water?
Yes, liquid nitrogen can be used to cool water. When added to water, liquid nitrogen evaporates rapidly, absorbing heat from the water and lowering its temperature. It is commonly used in laboratories and industrial settings for this purpose.
Is nitrogen a liquid?
Nitrogen is a gas at room temperature, but if brought to very low temperatures, it will condense into a liquid. Liquid nitrogen is fairly common and is used in several chemical processes, industries, and classroom demonstrations.
Why is liquid nitrogen used in beer cans over liquid oxygen?
The answer is, liquid nitrogen ISN'T used in beer cans. Nitrogen GAS is. And the reason nitrogen gas is used in beer cans is to emulate draft beer such as one would get out of a keg(as opposed to cask) beer.
