What is the purpose of using a wash buffer in a western blot experiment?
The purpose of using a wash buffer in a western blot experiment is to remove any unbound or nonspecifically bound antibodies or proteins from the membrane, helping to increase the specificity and accuracy of the results.
What was the purpose of adding three drops of chloroplast suspension to Cuvette 1?
The purpose of adding three drops of chloroplast suspension to Cuvette 1 was to provide the necessary chloroplasts for the experiment, as chloroplasts contain the photosynthetic pigments required for photosynthesis to occur in the experiment.
What is the purpose of the alcohol in the strawberry DNA extraction lab?
Hmm, I think it's used to wash the DNA from the substance used for extracting the DNA, such as Isopropanol, CLS, NLS, PPS which are used in the process of extraction to the process to precipitate the DNA (using isopropanol). DNA is insoluable in alcohol. Actually the real reason for using alcohol in a DNA extraction is to "precipitate" (NOT RAIN) the DNA, as you may have realized when you did the experiment , the Alcohol step is the last step that brings the DNA to the surface. Finally alcohol can be added so that the DNA can be seen, but first it is crucial to know why the addition of alcohol is such an important step. This step is closely related to a process called precipitation, which is " the process of separating a substance from a solution as a solid" (answers.com, precipitation). Precipitation separates the DNA so that it can no longer remain dissolved and so that it can be seen. DNA is less dense than water and alcohol , so the DNA rises to the alcohol layer. Also the DNA is soluble in water and insoluble in alcohol, so when it is just in the mixture it is quite invisible but once the alcohol is added it condensates by precipitation to the point where it is very visible.
What is the color of the leaf at the end of the experiment that test for starch?
the color of the leaf become brown-black after the iodine solution was added.
What is the correct definition for controlled experiment?
A controlled experiment is a scientific study in which one variable is manipulated (independent variable) while all others are held constant, to observe the effects on another variable (dependent variable). The purpose is to determine causation between the variables being studied.
What is purpose of doing an experiment?
the purpose of doing an experiment is to discover new things
What is the purpose of alcohol when extracting DNA?
According to me, we use alcohol because DNA is insoluble in alcohol, it aggregates together, giving a pellet in centrifugal and we can see a precipitated DNA with naked eyes (that we suppose to see in experiment i.e DNA extraction)....
What is the chemical formula for rubbing alcohol?
There is no exact formula. Denatured alcohol is mostly pure ethanol (drinking alcohol) which has had something added to make it poisonous (denatured or unnatural) so that it cannot be drunk. Different substances can be added for this purpose... thus no formula.
The factor in an experiment that is changed on purpose?
The factor in an experiment that is changed on purpose is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable. It is the cause being studied in the experiment.
What states the purpose of a experiment?

What would a scientist do before designing a experiment?
Be clear about the purpose of the experiment.
What is the purpose in a science project?
A purpose is why u are doing an experiment
Is purpose and hypothesis?
The purpose is why you are doing the experiment. What do you want to fond out?? The hypothesis is your prediction on the outcome of the experiment. It is usually written in an If...Then...Because form
What is the purpose of the dry ice bubble experiment?
the purpose is how is is getting bigger
What is the independent variable in an experiment designed to investigate the effects of alcohol consumption on memory?
In this experiment, the independent variable would be the amount of alcohol consumed by the participants. Different amounts of alcohol would be administered to different groups to observe the effect on memory.
