title: Calculation of probabilities of random occurrence of different types of palindromes.
abstract: Formulas for the calculation of probabilities of the random occurrence of different types of true and complementary palindromes in DNA of arbitrary nucleotide composition were proposed. Calculations using the formulas developed show that the probabilities of random occurrence depend significantly, as expected, on the combinatorial restrictions, imposed on the palindromes, and in some cases also on the nucleotide composition of the DNA. Calculations performed demonstrated that even comparatively short (6/8 etc.) palindromes of certain types could ensure the required specificity of the protein-DNA interaction in transcription, replication etc.
