Molecular Biology

We receive from our parents not only their DNA, but complete chromosomes. These are surrounded by proteins (histones). These are also passed on. Thus, far more information can be transferred from parents to offspring than was previously assumed. It remains to be seen, however, to what extent this information will lead to epigenetic changes being inherited. This is a research approach that we are investigating primarily by means of molecular mechanisms of the cell membrane.
Which characteristics are inherited by daughter cells is therefore not only dependent on the DNA sequence. Chromosomes or individual genes can be significantly influenced in their activity. This is called "epigenetic imprinting". The DNA sequence is preserved but modified and often "silenced" (DNA methylation or alteration of histones).

Thus, everything fundamental is fixed in the DNA, but it seems possible to modify or rewrite this by environmental factors in the broadest sense.
