| The discrepancies of molecular structure between DNA and RNA result to their different nature. Deoxyribose constituting DNA is more hydrophobic than ribose constituting RNA. On the chemical principle of similar substances can be soluble with each other (SSSEO), here, I propose that the DNA, nucleoplasm, and decondensational state of chromatin are more hydrophobic than the RNA, cytoplasm, and condensational state, respectively. Based on this point, many biological processes, such as the disappearance and reappearance of nuclear envelope during division of eucaryote, the spontaneous exit of RNA to cytoplasm after synthesis within nucleus, and the relation between chemical modifications of chromatin and some important cellular processes, may be well explicated. |
