CATDOLL : CATDOLL: How do prions reproduce?

1. How do prions reproduce?

Some scholars believe that prions multiply through information flows that are different from the central dogma of biology. It may be that PrP (viral protein) is first translated into RNA or DNA, and then the daughter PrP is synthesized. This process requires reverse translation enzyme and reverse transcriptase, and the former enzyme has never been discovered.

Bad Mechanism: The fate of a healthy protein when it comes into contact with an infectious prion - the good protein becomes a prion and becomes infectious. In other words, a good protein becomes a bad guy and there is no return. This rapid change of face provides important information for uncovering the secret molecular mechanism of prions.

4. What are the ways to eat razor clams?

Put the clams in socks, pour in clean water, and scrub with a bamboo brush (scrub continuously without interruption to prevent the clams from absorbing muddy water) until the shells turn white, pour out the muddy water, and then clean them with clean water. Put them in boiling water to blanch them slightly (don't blanch them too much, otherwise the meat will turn purple and lose its flavor), and then take them out. If the shells are difficult to peel, turn the clams over a few times, and then put them in boiling water to blanch them slightly. Peel off half of the shells of the clams, put them in a plate, sprinkle with minced ginger and chopped green onions, and pour with soy sauce, wine, and sesame oil.

5. The reproduction method of Hainan tiger bittern

The nesting place of the Hainan Tiger Bittern is in Liuzhou, Guangxi. It chooses to build its nest on the tree beside the stream in the deep mountains and dense forests where few people go. In Qiandao Lake, Zhejiang, the Hainan Tiger Bittern also chooses to build its nest on the small island in the middle of the lake where no one disturbs it. Qiandao Lake in Zhejiang is the largest breeding place of the Hainan Tiger Bittern found in China. During the breeding season of the Hainan Tiger Bittern, it is very afraid of being disturbed by humans. Once there is an abnormal noise, it stretches its neck and looks around vigilantly. Its nest is similar to that of other heron birds. It is built into a shallow dish with dead branches commonly seen around the nesting site, with a diameter of about 40 cm. Each nest contains 2-4 eggs. From the parent bird nesting to the chicks flying out, the entire breeding period of this bird is about 4 months.

6. How do coconuts reproduce?

Coconut propagation: seed propagation. Fully mature coconuts will begin to germinate in more than two months as long as there are appropriate temperature and humidity conditions. Hainan generally adopts the method of germination in a preparatory nursery. Choose a semi-shaded, ventilated, and well-drained environment, remove weeds and tree roots, plough to a depth of 15-20 cm, dig a ditch that is slightly wider than the fruit, and place the fruit one by one at a 45° angle against the bottom of the ditch, burying the soil to one-half to two-thirds of the fruit. When the buds are 10-15 cm long, move them to a nursery with moderate shade, and pay attention to watering, drainage, weeding, and fertilization. Generally, after about a year, the seedlings can be transplanted when they are about 1 meter tall.
