It is not a secret that parents transfer not only certain genetic material to their children, but also certain genes that work in a certain way – but many researchers are very interested in the question of whether certain patterns of behavior and development of genes can be transferred via DNA. This is exactly what the team of microbiologists from Princeton University today took up, presenting at the same time the preliminary results of their rather long study – with very unusual indicators. In particular, the basis of the new experiment was the desire to find out whether worms can transmit to each other certain bacteriological patterns.
To be more precise, can donor-worms, from which certain biological and genetic material have been removed, transfer their patterns of behavior to avoid certain bacteria to the worms that served as patients. What the team of researchers from Princeton did, carrying out the transfer of a certain part of the RNA worms of the C. elegans family to other worms from the same group — the basis of this RNA complex was information about the need to avoid some bacteria with which the worms donated but which the patient worms did not concern.
It turned out that the patient worms, who integrated the RNA-complex of donor worms, in most cases began to demonstrate exactly the same behavior patterns as their donors – so the study somehow confirms the previous theory that DNA transfer patterns and gene expression is indeed intergenerational.
However, it is not quite clear whether the same principles will work on more complex organisms, such as man, for example. Because conducting experiments and experiments on worms allows the use of a relatively small amount of materials and substances, which makes this kind of experiment quite easy. At the same time, scientists believe that about the same results can be achieved in human studies.
