Both sexes mating sperm will change to "packaging"

Original essence, eggs tryst, sperm before go to bed. Mr. Also must first change "pajamas". This is the French scientists recently new research findings.

Published in the latest issue of the journal nature, said the report: through the animal testing found that in reproductive stage, the sperm of DNA is need to replace their "packaging". The change "appearance" sperm DNA, ability and eggs is possible DNA combination, can be born new life.

In this paragraph may report people understand not deep, or can't understand. Now I will give you a visual reading:

Chinese name the DNA of the DNA, is a long chain molecules, it is and the creatures of the genetic material, is it contains the tens of thousands of genetic genes. In each of the nucleus has a set of DNA. However, the human body cell and reproductive cells of the DNA is different, somatic cell nuclear DNA is double chain, a cold chain from the father, a cold chain from the mother. But good and eggs in the nuclear DNA is the single, this is the two at fertilization of single DNA fuses in together, forming the fertilized eggs double-stranded DNA, which then split the formation of new life of somatic genetic material is not each half from parents?

But the DNA chain like snakes seems to have rickets, it must be wound in a group called the protein molecules in cell nuclei exist on a chromosome, can put the group as the DNA protein coat or packaging. To this group before packing protein recognition, not deep, new research discovered that the original packaging is not the sperm of coat of protein, but pure protein. Sperm in the body of the extraordinary at ordinary times exquisite showily coat, like the cock luxuriant feather, there seems to attract the role of eggs. But true to the secret rendezvous, eggs does not buy it this girl dress of his body, fine sir must honestly take off of lean protein to dress, change and the eggs of the same group of protein girl pajamas, to go to bed and meadow, which combines into a fertilized egg, new life, was born.

The new findings also found a gene called HIRA, it in the new life the most key stage have played a key role. In sperm need to close to egg, it will make the encoding commands histone timely replace sperm of DNA of lean protein. But the new change group of female reproductive cells of the protein and histone no difference, so the combination of sperm and egg is easier.

This means that the gene HIRA to the human society "matchmaker", is she the girl that rhetoric eggs quietly accept change clothes of sperm to go to bed after Mr Peace.

The study also found that, the slight variation HIRA genes will prevent the formation of embryos. This further shows that the gene in the reproductive process HIRA importance. And how about this XinShu error as those matchmaker, her lips in the strike could put a couple scattered said. You see, the human body the microscopic and the phenomenon of human society how similar. This is probably the human genetic roots?

The research results, no doubt on reproductive research, especially for healthy birth to research and solve the study of infertility a massive role.
