Homochirality and related problems have been reviewed. Relative probability of different versions of homochirality arising were estimated on the example of processes, synthesis of organic compounds in space, asymmetric photolysis under circularly polarized light, synthesis of optically active compounds as a result of parity violation, magnetochiral dichroism, chiral amplification, optical active amino acids synthesis and theirs isotope ratios in meteorites, and some other determinate and indeterminate processes. It has been estimated handedness of moving objects as source of chirality. Possible contributions of these processes in homochirality origin in nature have been evaluated. The view is justified that homochirality (and life) origin may be not an accidental event.

Keywords: Asymmetric in vitro and in vivo reactions, enantioselectivity, homochirality.
