The monkey has a mother and a father

According to the August 27 issue of DailyMail , US scientists took advantage of IVF technology to successfully modify the genetic defects of DNA. They created four healthy monkeys that genetically modify.

What surprised everyone is that these monkeys have 2 mothers and one father. Scientists say, by this technology, will be able to produce genetically modified babies in the next few years.

The first American scientists took an egg cell from a mother monkey with DNA that carries hereditary disease, then removed the gene that could lead to hereditary disease and transplanted the DNA nucleus into healthy egg cells of a mother monkey other. Previously, the DNA nucleus of oocytes in mother monkeys was separated. So scientists have obtained a mixed egg cell . Then continue to carry this egg cell and the father's sperm to conduct in vitro fertilization, thereby creating a healthy monkey. Thus, physiologically, this monkey has two mothers and one father.

Scientists say that cells must be supplied with new energy to survive, while mitochondria are the bodies that generate energy for cells. Each mitochondria contains a small DNA sequence, carrying 37 to 20,000 different genes. Mitochondrial DNA can only be passed through mother monkey eggs. The medical community has determined that there are about 50 types of genetic diseases caused by mutations of mitochondrial DNA.

While the medical community welcomed this groundbreaking research, moralists proved extremely worried. Josephine Quintavalle of Comment on Reproductive Ethics said: ' Production is a genetic work, we should not interfere with any cost of the reproductive process that has evolved for millions of years. Although the purpose of the study is to prevent mitochondrial disease for the next generation, this project will probably bring very disturbing results. '
