The method of making dumplings
Processing method
1. Raw oysters: Sifted ash, picked up impurities, crushed the sieve, or cut both ends.
2. Yamagizutake: Take a net of medlar, cut it with a pair of scissors, and peel off the skin to get it.
3. Hawthorn skin: The exocarp peeled off by medlars.
4. Fry the dumplings: Take the crushed dumplings, set the pan and stir fry until golden brown, remove and let cool.
5. Jiao Xiezi: Take the crushed glutinous rice dumpling, set it in a pot and stir it with a small amount of fire. Remove and let cool.
6. Scorpion charcoal: Take crushed dumplings, set the pot and stir-fry until it dark brown, but the need to exist, remove and let cool.
7. "Leigong Artillery Paradox": Where to make dumplings, peeled first, take the benevolence, immersed in licorice water overnight, baked out, dried, sifted, such as the use of red gold.
PCR ( Polymerase Chain Reaction)
It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
Superyears General 2215 RT-qPCRadopts all-in-one with an industrial art design, combining the Analytical Instrument, Large touch screen, and Computer. General 2215 RT-qPCR is equipped with the proven thermal-cooled electric technology, which can recognize the speed rate of temperature control faster and obtain high-quality testing results within 40 minutes.
