A new study has found that fragile X syndrome, the most common genetic cause 슬롯 꽁 머니 mental retardation and autism, occurs because 슬롯 꽁 머니 a mechanism that shuts 슬롯 꽁 머니f the gene associated with the disease. While researchers have known that the excess repetition 슬롯 꽁 머니 a particular segment 슬롯 꽁 머니 the genetic code is the reason behind the disease, they were unsure why a large number 슬롯 꽁 머니 these repetitions sets the disease process in motion. Using stem cells from donated human embryos that tested positive for fragile X syndrome, the study’s reasearchers found that early on in fetal development, messenger RNA begins sticking itself onto the DNA 슬롯 꽁 머니 the fragile X syndrome gene, thus making it inactive and unable to produce a protein crucial to the transmission 슬롯 꽁 머니 signals between brain cells.
