Genes relocated from their correct position in the nucleus cause them to malfunction and this may lead to the heart, blood vessels and muscles breaking down.Singapore,
DNA is under constant attack, from internal factors like free radicals and external ones like ionizing radiation.
The most detailed annotation yet of the fruit-fly genome points the way to understanding the genomes of all organisms.
A gene which is essential for stem cells' capabilities to become any cell type has been identified by researchers at the Hebrew University of Jerusalem and the University of California, San Francisco.
The DNA of a mammalian cell is about two metres long if all base pairs were aligned in one string. To fit this genetic material in a nucleus of only a few microns diameter, the DNA is wrapped around millions of so-called histon proteins that are arranged like pearls on a string, leading to a 10,000-fold compaction of the DNA.
The eyes of nocturnal mammals have very large numbers of highly-sensitive rod photoreceptors (the cell type responsible for night vision). They have to perceive light which is less than a millionth of the intensity of daylight
Researchers have discovered an important element for making night vision possible in nocturnal mammals: the DNA within the photoreceptor rod cells responsible for low light vision is packaged in a very unconventional way
