'Start of life' gene discovered
Scientists have found the gene responsible for controlling a first key step in the [pro]creation of new life.
"Lead researcher Dr Tim Karr, from the University of Bath, said: 'All sexually reproducing animals do the same kind of DNA 'dance' when the DNA from the mother's egg cell and the father's sperm cell meet for the first time.'
When the sperm enters the egg, its DNA has to undergo a complete transformation so that it can properly join with the female DNA to form a genetically complete new life.
Sperm makes this change by swapping the type of 'packing material, known as histone proteins, it contains.
The result is called the male pronucleus, which can then combine with the female pronucleus. "
"A slight mutation in the HIRA gene means that life does not even get started."
Simply amazing.
