[Effect of individual factors of the space environment on the abiogenic synthesis of nucleotides].

Key role of thermal energy has been shown in abiogenic synthesis of natural nucleotides (deoxyadenosine and cytidine monophosphates) in a solid phase during phosphorylation of deoxyadenosine and cytidine at the board of the orbital station "Salute-7" (temperature from -50 to 65 degrees C, exposition for 13 months) and in laboratory experiments (temperature 65 degrees C, exposition from 8 days to 6 1/2 months). The results obtained are discussed in relation to possible contribution of thermal energy in processes of prebiological evolution on the lithosphere of the Primitive Earth and various cosmic bodies.
