چکیده
|
There are fundamental questions in biology having a proper knowledge of their various dimensions, can improve our understanding about the nature of living matter. what is entangled with these matters, resembles veiled reality that scientific developments scratch it continuously. then, it makes possible to retrieve the truth from such encrypted context. the problem of origin of life is one of the fundamental challenges in the history of science. there have been permanent efforts among researchers of various branches, including chemists, physicists and biologists to make a lucid explanation of this everlasting problem. living systems must differentiate between various patterns of the same kind. one of the realizations of such asymmetric detections is chirality of biomolecules.when a molecule cannot be superimposed on its mirror image, it is said to be chiral. chiral molecule and its mirror image are known as enantiomers. chiral states are not stationary states of the hamiltonian but they are absolutely stable! all the sugars and amino acids can be find exclusively in right and left configurations, respectively, which are the superposition of electronic eigen states of the hamiltonian. we face with one kind of features of natural selection in which a schrodinger’s cat exclusively is forced to be collapsed to one of its choices dead or alive. emergence of chirality cannot be explained with theories just based on the molecular hamiltonian. since it is a product of symmetry breaking and hamiltonian commutes with parity operator. what are the mechanisms incorporate at molecular level, which are responsible for neo-darwinian problem of chiral selection in biology? we try to elucidate different aspects of it with the language of quantum mechanics.
