Scientists Unpick Genetics Of First 15 Minutes Of Life
Scientists Unpick Genetics Of First 15 Minutes Of Life: "THIRA, ‘chaperones’ the early processes that take place once a sperm enters an egg, giving it a crucial role in the most fundamental process in sexually reproducing animals.
The absence or mutation of this gene in the maternal (mother’s) genome explains why eggs fail to produce a zygote – or early embryo - despite the presence of ‘healthy’ sperm.
The researchers looked at the genetic makeup of the sésame mutant and identified what is known as a point mutation in the HIRA gene -- showing that HIRA is the gene responsible for chaperoning the assembly of the sperm pro-nucleus."
