Why are strawberries good to use in a DNA extraction experiment?
Strawberries are good to use in a DNA extraction experiment because they have 8 times the amount of DNA than the average cell.
Was this answer useful?
Thanks for the feedback!
liquid nitrogen (-170 C) which it freeze the tissue to become fragile to be a fine powder which increase the surface area of extraction, and the very low temperature prevent D…Nase activation * the primary function of this step is to lyse the cells
MgCl2 is used to preserve the integrity of membrane system by counteracting the fixed negative charges of membrane phospholipid. Depending on what you want to extract, i…t tries to protect the component you are interested in (DNA/RNA/red blood cells, etc) from being lyzed by broken-open lysosome for instance.
You could have plain fruit. Otherwise, fruit is really good mixed in (in the mornings) with cereal, oatmeal, and pancakes. (You can have all of these with vegen ingredients, l…ike soy milk.) For a snack, you could make a strwberry smoothie / milkshake. (Strawberries, soy milk or vegen ice cream, little bit of sugar, ice cubes, put it in a blender and enjoy!) Fruits can be mized in with salads, put on sandwiches, or used to make dressings and glazes. Strawberries and other fruits are nice atop vegen desserts (cakes, cookies, ect.), or just plain, too.
Well, scientists can use extracted DNA for many uses. They can find out who was involved in a murder case, they can find out how different two different sets of DNA are, disor…ders, etc...
It helps break the nuclear membrane of the cell. Detergent containing the compound SDS ( sodiumdodecyl sulfate) is used to break down and emulsify the fat and proteins that m…ake up a cell membrane.
It serves to break the tissue apart so the DNA can be subsequently extracted.
A ripe strawberry has several million tender cells with delicate cell membranes. These cell membranes break easily. Since one of the first steps of DNA isolation is to break …open the cell, delicate cell membranes are beneficial
Although it it a bad idea to use something as unregulated as dish washing liquid for DNA isolation, the scientific principle is that proteins denature (or break up) in the pre…sence of a detergent. Denatured proteins can then be separated from the remainder of the cellular contents by centrifugation. This leaves a supernatant containing mainly nucleic acids (DNA and RNA) Dish washing liquid is unregulated because we do not know exactly what is in there since it is a commercially available product. There could be other ingredients (like fragrances and other appearance enhancers) that might interfere with DNA isolation. Laboratory grade detergents like SDS and CTAB are used for DNA isolation
Detergent is a dehydrating agent that allows the DNA to precipitate. Precipitated DNA can then be separated from the other components through a process called centrifugation.
It breaks down the Cell Membrane, making it easier for the DNA to come through. Good Luck :)
I'd assume because it has a lot of cells suitable for DNA extraction. I don't really know, we've always used strawberries because if the high amount of seeds in a small space.…
The DNA is inside the cells and we have to make that DNA to go into the solution so we crush it
Because the phosphorus group is more susceptible to change than in a strawberry DNA.
Maybe because bananas are annual kind of plant, which means they can survive in all year round in both rainy season and summer season and it's easy to produce unlike to the ot…her plant to our surroundings. On the other hand, bananas have a juicy stem or body, it has a complete structures of genetic information and besides banana can reproduce itself, without mating from the other plant nor from the other species of banana.(asexual reproduction).
The reagents used in DNA extraction contains salts that help buffer the respective reagents. Toward the end of DNA extraction, it is necessary to wash away these salts in orde…r to obtain clean DNA for further experiments. Therefore, wash buffer is used for DNA extraction
The reason why isoproponal is used in DNA extraction is because it is stronger at precipitating the DNA. DNA is also insoluble in isoproponal and is cold to help the DNA retai…n its shape.
It is a polyploid fruit i.e. it has several sets of chromosome complements as a result of scientific intervention. This results in a high DNA content. Also, the pulp is ea…sily broken down meaning the cell walls and membranes can be more readily disrupted thereby releasing more genetic material.
