Gene silencing is a highly conservative, sequence-specific mechanism for the removal of DNA from eukaryota, such as plants, animals, nematodes, and fungi. It was discovered in 1990, when researchers introduced more copies of genes related to the synthesis of pink dye into petunias to produce darker purple petunias. As a result, many flowers did not deepen, but instead turned white or white. It plays an important role in regulating development and maintaining the stability of the genomes in response to biotic and abiotic stress. In eukaryota, there were many application methods according to the duration of the silencing of the DNA. It had important applications in plant functional genomes research, crop quality improvement, and virus-resistant plant cultivation, and had good development prospects. In the medical field, in 2018, the US Food and Drug Administration approved the first RNai-based drug, ONPUTL, for the treatment of hereditary transthyretin beta-like degeneration (hATTL) associated with multiple neuropathic diseases. In the agricultural field, the DNA pesticide was based on the mechanism of DNA interference. Compared with traditional small molecular pesticide, it had strong target specific and no residue, and the development cost was much lower than that of chemical pesticide. The first pesticide product approved by the U.S. environmental protection agency was a genetically modified corn that expressed DvSnf7 double-stranded R A to control the Western corn rootworm. The product was scheduled to be available in 2024. In addition, the VT4PR corn produced by the Bayer Group with the use of the Ai technology was also registered by the EP A and would be available in the United States as early as 2024. However, in order to realize the large-scale application of R A interference technology in the prevention and control of pests, problems such as the efficiency of R A delivery to target cells, the silencing efficiency of target genes, dose-limiting toxicity and insufficient interference efficiency, and the stability and persistence of R A molecules needed to be solved.

The complete collection of the methods of Internet celebrity shumai

The following are some methods of making shumai: ** 1. Prepare the basic ingredients ** 1. Glutinous Rice Treatment - The glutinous rice could be soaked in advance for 1 - 3 hours or overnight. After soaking, drain the water and put it into a steaming plate or an electric rice cooker to steam it. The amount of water controlled was different. For example, when the electric rice cooker cooked glutinous rice, the water was slightly less than usual, or the amount of water just exceeded the glutinous rice. The steaming time was about 20 minutes. During the steaming process, small holes could be made on the glutinous rice to speed up the steaming. 2. Prepare the filling ingredients - Common fillings included onions, mushrooms, carrots, green beans, corn, cooked diced pork, salted egg yolk, meat floss, cheese, and so on. Among them, the shiitake mushrooms could be diced, the onions could be diced, and the carrots could be diced and stir-fried with the shiitake mushrooms. If salted egg yolks were used, they could be used after the egg yolks were removed from the raw salted duck eggs, sprinkled with wine, and baked in a 180-degree oven for five minutes until the surface turned yellow. They could also be used directly by purchasing ready-made salted egg yolks. ** 2. Stir-frying and seasoning the fillings ** 1. Stir-frying sequence - After the oil in the pot was heated up, he first put in diced onions and stir-fried them until they were fragrant. Then, he added diced shiitake mushrooms (if there were diced carrots, you could also add them at this time) and stir-fried them until they were done. Then, he added in corn and green beans and stir-fried them a few times. Then, he poured in steamed glutinous rice. He could also stir-fry the diced meat first to produce the fragrance, then add the shiitake mushrooms to stir-fry the shiitake oil, and then add other ingredients. 2. seasoning method - Seasoning usually included salt, first-grade fresh soy sauce, dark soy sauce (used for coloring), oyster sauce, five-spice powder, light soy sauce, etc., and sugar and other seasonings could also be added to adjust the dosage according to personal taste. ** 3. Preparing and wrapping the dough ** 1. Face Selection - You can use dumpling skins or roll it with flour and water in a 2:1 ratio. 2. Wrapping Method - He wrapped the stir-fried filling into the dough. If one used the dumpling skin, just like how one would wrap a steamed bun, one could pinch the edges into a circle of folds. One could not pinch the fish mouth in the middle, which was the shape of an open steamed dumpling. One could also pinch the edges into the middle with the tiger's mouth of one hand and put them away. You can also put a layer of glutinous rice first, then put in meat floss, salted egg yolk and other fillings, and then cover the fillings with glutinous rice before wrapping them. ** 4. Steaming ** - The wrapped shumai was steamed in cold water. After the water boiled, it was ready to be steamed for 8 - 10 minutes. If it was a frozen shumai, he could just take it out and steam it before eating. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
