How are RFLP made?
A DNA sample is broken into pieces by restriction enzymes and the resulting fragments are separated according to their lengths by gel electrophoresis. RFLP analysis was the first DNA profiling technique inexpensive enough to see widespread application. But isn't as widely used now.
Where in the gel electrophoresis do you find larger fragments?
The larger the fragments the slower it migrates through the gel. Because it is bigger it takes longer to squeeze through the pores of the gel matrix. So the largest gel fragments will be at the top, closest to where the sample started.
What technique is used to obtain uncontaminated urine sample?
Clean Catch or Catheter
Who might use aseptic technique?
microbiologist,biologist and everyone that need to get a clean sample(prevent adding bacteria to the sample).
Name a technique that could be sucessfully employed to sample the organisms living in a tree?

What is external standard method for chromatographic technique and how to perform it?
In external standard method we run a standard for the substance we are looking for in our sample and than run our sample in the same conditions. we will obtain peaks for the sample and standards and can correlate the sample with the standards and can determine the concentration of the same in our sample. for more details contact vani2007
What is radiometeric dating?
Radiometeric dating is a technique to date geological materials like rocks etc by determining the relative proportions of particular radioactive isotopes present in a sample.
How do scientist use radioactive elements to determine the actual age of fossils?
scientist can determine a fossil's age in two ways: relative dating and absolute dating
What is hydrogen bubble technique in measuring the isotropic line?
The hydrogen bubble technique involves placing a small amount of hydrogen gas near a sample in an NMR spectrometer. The hydrogen gas creates bubbles that help determine the isotropic line (line width) of the NMR signal, which can provide information about the sample's molecular motion and interactions. This technique is particularly useful in studying dynamics in solution NMR spectroscopy.
What is the smallest sample size in research technique?
One.
What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
What technique is used to collect a tissue for biopsy of the prostate?
The tissue sample can usually be obtained with the needle technique.
How would you distinguish a sample of peat from a sample of mudstone that contains fossil plant fragments?
Peat would remain largely unconsolidated. Mudstone is a rock.
How do you determine an adequate sample size?
A sample size is needed whenever you conduct an experiment. How you determine an adequate sample size depends on the scope of what you're testing, such as medications.
What is the separation techniques for sublimation?
The technique is simple: heating of the sample.
The most rigorous technique for selecting a polling sample is?
straw
Is descriptive data a technique?
No, descriptive data is not a technique; it is data that describe the sample such as mean, SD, mode, and range.
