That effort, along with those of other investigators, has led to identification of a gene whose mutation can cause the arrhythmia. Those […]
Massive decoding effort reveals fruit fly DNA
An enormous effort to decode the DNA of one of the most important laboratory animals, the fruit fly, ended in success this week as a collaboration of researchers from 16 nations announced the sequencing of 10 fly species’ genomes. The research allows the extraordinary side-by-side comparison of the DNA of 12 species of […]
All human beings are not genetically similar.
A new study has found that the genetic variations in the humans are different from what had been discovered earlier. Gene mapping of an individual, which is claim to be the first, has found this new result. Until now the mappings were not based on an individual but were performed on human tissue samples that do not […]
