A World Health Organization Report of 2008 stated that ‘A girl born today can expect to live for more than 80 years if she is born in some countries - but less than 45 years if she is born in
I am no biologist, but as a physicist, a spontaneous mutation (seen as a chemical transformation) should lower the energy of the system, at least locally. So I wonder if any research has been done a
At the end of 2009, an estimated 20,171 people were living with a HIV diagnosis in Australia. From the start of the epidemic until the end of 2009, there had been 29,395 diagnoses of HIV and 10,446

My understanding and experience is that during the night photoreceptors are less tightly coupled to the retinal pigment epithelium.
As we have heard in the summaries of the human ENCODE project, 80 per cent of junk DNA appears to have an essential function. Many fish have a genome with only one tenth the size of a usual vertebra
I've been reading a bit about "junk DNA" and how much of our genome consists of this "non coding DNA" in comparison to "coding DNA".I'm just an interested layperson but I thought all combinations of
The DNA copying enzymes have a hard time working to the end of a chromosome. For circular chromosomes this is not a problem, since there is not a sharp 'end'.
It is well known that the first DNA polymerase, Taq, is quite error prone. Newer generation commercial enzymes that have either been isolated from different thermophile species or have been improved

Eventually, Joan and Mary decided to start a family.They heard about DNA testing: a new family planning procedure using DNA samples to screen for possible genetic differences that could affect their
If a DNA-binding protein "reads" a short stretch of DNA and detects the following "second" genetic code provided by the functional groups located on each base as H-HD-CH3-HA-HA-HA-HA-HD,
a proportion .01 of a population has a gene (G) that confers susceptibility of moldy looking green teeth.
