Question
Genotyping of a taste receptor polymorphism by PCR-RFLP.Consider DNA purification and put the steps in the correct order.
Solution
Sure, here are the steps for DNA purification in the correct order, which is a crucial part of genotyping a taste receptor polymorphism by PCR-RFLP:
-
Cell Lysis: This is the first step in DNA purification. The cells are broken open to release the DNA inside. This can be done using a lysis buffer, which breaks down the cell membrane.
-
Protein Removal: After cell lysis, proteins and other cellular debris need to be removed. This can be done using a protease (an enzyme that breaks down proteins) or a protein precipitation solution.
-
DNA Precipitation: The DNA is then precipitated out of the solution using alcohol. The DNA will form a solid that can be seen in the solution.
-
DNA Wash: The precipitated DNA is then washed to remove any remaining impurities. This is usually done using a wash buffer.
-
DNA Elution: The DNA is then eluted, or removed from the solid phase into a solution. This is usually done using an elution buffer.
-
DNA Quantification: The last step is to quantify the DNA to ensure there is enough for the PCR-RFLP process. This can be done using a spectrophotometer.
After the DNA is purified, it can be used in the PCR-RFLP process to genotype the taste receptor polymorphism.

One of the SNPs of a certain bitter taste receptor (TAS2R38) was investigated by PCR-RFLP method using the Fnu4H I restriction endonuclease. If the C allele is present as a template, the enzyme cleaves the PCR product amplified from it at the SNP, and the PCR product always contains two additional non-polymorphic cleavage sites. In the upper, schematic part of the figure, the cleavage sites in the expected PCR product are shown by bold arrows, and the distances between them and from the ends are shown by numbers.
