I believe lactic acid fermentation is used for all three!
Definition
A technique which is used to separate, DNA, RNA or protein pieces from each other under the influence of electric field on the basis of their molecular size is known as gel electrophoresis.
Explanation
This method is very reliable for separation of large size molecule (over 1 million Da). Materials which are required for gel electrophoresis include:
1. TAE stock buffer
2. 1% agrose gel
3. Nucleic acid loading dye
4. Ethidium bromide
Procedure:
First prepare a stock solution of TAE buffer by adding appropriate amount of TAE in distilled water. then prepare 1% agrose by adding 1X TAE, some amount of agrose in water and heating it in microwve oven to mix them will. then pour agrose gel on tray and fix comb in it and keep it untill agrose dry. Then remove comb and pour some quantity of nucleic acid along with loading dye and ethidium bromide in each well. EtBr is used for staining nucleic acid.
When sample is poured in all well also pour reference marker in one well for comparison. now connect it with voltage for 30-35 min. After this take gel and see it under UV. a large number of nucleic acid pieces will be seen on gel under UV. those pieces which have small molecular weight will cover more distance compared to those having larger molecular weight.
The allergic reaction in which it produces this type of
reaction due to cosmetic or chemical is called the dermatitis venenata. The
dermatitis venenata, enables to form an inflammation on the person’s skin because
of various causes such as mineral substances, chemicals, cosmetic products and
other surfaces that may be of contact to the skin in which it causes the skin
to cause inflammation.
Answer;
-They are absorptive interfaces with the environment.
Explanation;
-The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
-The surface area to volume ratio of an object is the relationship between two measurements. It is the ratio of Surface area to volume. It shows the comparison between the size of the outside of an object and the amount inside. Small or thin objects have a large surface area compared to the volume.
