A recent discovery on genetic repair has been published in the journal Proceedings of the National Academy of Sciences. The Uppsala researchers presenting their new finding that used minibacteria and ants.
Insects like ants, tse-tse flies, and aphids known to be dependent from special minibacteria for their survival. The bacteria live in special organs inside insect’s bodies, and packed into the eggs of insects to be spread to the next generation. It is very funny knowing that in this cycle, a great deal of genetic damage takes place.
The minibacteria’s genes are successively degraded, these damaged genes should no longer be able to function because the genetic damage arises during copying of the DNA string in the mother cell to the new DNA strings in the daughter cells.
But study showed, the damaged genes become protein. This the reason why they concluded that repeated errors in the conversion of DNA to protein save the function of the damaged genes.
