China's achievements in cloning technology.

In June, 2000, China Northwest A&F University cloned two "cloned goats" from adult goat somatic cells, and one of them died prematurely because of respiratory system dysplasia. It is reported that the cloning technology adopted by the research team is completely different from Dolly's cloning technology, which shows that Chinese scientists have mastered the cutting-edge technology of somatic cell cloning.

201March 18 In the early morning, the embryo engineering and reproductive technology laboratory of Beijing College of Animal Husbandry and Veterinary Medicine of China Academy of Agricultural Sciences obtained somatic cloned cattle by caesarean section in Changping experimental cattle farm. The cow was pregnant for 279 days and weighed 58.2 kilograms at birth. At present, all physiological indexes are normal. The cloned offspring were identified by Beijing Huada Fang Rui Identification Center, which was completely consistent with the cell-derived donor bovine DNA.

The main classification of cloning:

1, human body art cloning

Human artistic cloning is completely different from medical cloning. Here we borrow the concept of "replication" of cloning. This not only sounds novel, but also easy to remember. More importantly, only the word "cloning" can accurately and truly highlight the excellent characteristics of this technology.

2. Animals and plants

Many plants have a natural ability to clone. For example, if you cut a few branches from a big willow tree and put them in the soil, the branches will grow into lively and lovely willows; If you cut potatoes into small pieces and plant them in the ground, you can harvest a lot of fresh potatoes.
