3.2 Mirko Beljanski and RNA Fragments
We have seen that in the cell, DNA is like a library containing all genetic information. But what activates DNA, and what makes it enter into mitosis (the multiplication of the cell)? And, on the other hand, what are the factors that put the DNA to rest or block it, and thereby prevent it from working normally?
Biologist Mirko Beljanski (1923-1998) specifically studied DNA activity.1 Many chemical factors, like hormones, can activate cell DNA through binding at specific sites. Conversely, poisons and heavy metals, as well as gamma and X-rays, are capable of...
