Latest Gene duplication Stories
Researchers at the SIB Swiss Institute of Bioinformatics and the EMBL-European Bioinformatics Institute have confirmed the long-held conjecture that studying the genes we share with other animals is a viable means of extrapolating information about human biology.
What can a fish tell us about human brain development?
The human brain is the center of the human nervous system and has the same general structure as the brains of other mammals, but it’s than expected.
Scientists may have just found a ‘missing link’ in the form of a partial, duplicate gene that appears to be responsible for human brain development - the most distinguishing characteristic of our species.
A new approach to investigating hard-to-find chromosomal abnormalities has identified 33 genes associated with autism and related disorders, 22 for the first time.
Analysis of chromosome number variation among species of a North American group of prickly pear cacti (nopales) showed that the most widespread species encountered are of hybrid origin.
A new University of Florida study shows a hybrid plant species may experience rapid genome evolution in predictable patterns, meaning evolution repeats itself in populations of independent origin.
The anxiety and behavioral issues associated with excess MeCP2 protein result from overexpression of two genes (Crh [corticotropin-releasing hormone] and Oprm 1 [mu-opioid receptor MOR 1]), which may point the way to treating these problems in patients with too much of the protein.
An important part of saving a species is often understanding its DNA.
In children with genomic disorders, often a gamete – egg or sperm – has gone disastrously awry with either a duplication or deletion of genetic material that results in physical and neurological problems for the subsequent child.
