The real life of pseudogenes

Article Abstract:

Pseudogenes are considered as the molecular remains of broken genes, which are unable to function due to the lethal injury to their structure and a new insight provided by pseudogenes into dynamics of the processes by which genomes remodel and update themselves is presented. The findings reveal that certain cell-surface protein pseudogenes are reactivated when the organism is challenged by a stressful new environment.
