are few repeats or seemingly irrelevant filler sequences. "That even in a minimal genome every tenth gene is dispensable, has been a great surprise," admits Weigel. Detailed analyses showed that genes for basic cellular functions such as protein pr...
Identified main genetic variants involved in response to HIV
...spite humans sharing 99.9% of the genome sequence, there
are still 3 million genetic variations –which make us different from one another– 90% of which are due to SNPs. Hence, a good knowledge of these variations is highly valuable for the determination of the progression of AIDS. During the present stud...

is now a great deal of evidence that microRNAs themselves can act to either promote cancer or to stop cancer spread." To test their idea, the team first chemically damaged the DNA of two sets of colon cancer cells, one missing p53 and the other co...
