Chapter 5 Information three

In 1932, when Bei Shizhang, a famous Chinese biologist, was teaching at Zhejiang University in Hangzhou, he collected a small animal called Artemia in a place called Songmuchang.It is 1 to 2 cm long and very beautiful.Studies have found that they are neither male nor female in gender, a kind of intermediate sex.Further research made a surprising discovery: when the germ cells of Artemia intermedius underwent sexual transformation, the newly formed cells in the oocyte did not come from the division of the mother cell, but from the cytoplasm of the mother cell. Yolk granules are the foundation.The process is: the yolk granule first forms a new nucleus, and then gradually wraps the cytoplasm and cell membrane to form a complete daughter cell.

This is an extremely important discovery, which reveals the early process of the conversion of non-living matter to living matter on the earth in ancient times.Two years later, Professor Bei Shizhang formally proposed the theory of cell reconstruction for the first time in the world.It was only because of the war that the research had to be suspended, and it was not resumed until 1980. Professor Pei expressed the belief that in the 21st century, scientists will synthesize daughter cells from non-cellular substances in the laboratory, that is, transform non-biological substances into simple life.
