The artistic quality of a palindrome depends on the structure of a given language. In Russian and other European languages, palindromes usually sound artificial and unintelligible, whereas in Chinese, for instance, many highly artistic poems are palindromes. Examples of Russian palindromes can be found in V. V. Khlebnikov’s narrative poem Razin’s Boat and in works by V. Ia. Briusov, I. L. Sel’vinskii, and A. A. Voznesenskii. palindrome[′pal·ən‚drōm] (genetics) A nucleic acid sequence that is self-complementary. palindrome
pal·in·drome (pal'in-drōm), In molecular biology, a self-complementary nucleic acid sequence; a sequence identical to its complementary strand, if both are "read" in the same 5' to 3' direction, or inverted repeating sequences running in opposite directions (for example, 5'-AGTTGA-3') on either side of an axis of symmetry; palindromes occur at sites of important reactions (for example, binding sites, sites cleaved by restriction enzymes); imperfect palindromes exist, as do interrupted palindromes that allow the formation of loops. [G. palindromos, a running backward] palindrome (păl′ĭn-drōm′)n. A segment of double-stranded DNA in which the nucleotide sequence of one strand reads in reverse order to that of the complementary strand.
pal′in·dro′mic (-drō′mĭk, -drŏm′ĭk) adj.Etymology A word, phrase, number or other sequence of units that can be read the same way in either direction—adjustment of punctuation and spaces between words is permitted
Molecular biology Inverted repeat A sequence of duplex DNA or RNA with dyad symmetry that reads the same in the 5’ to 3’ direction on complementary strands; DNA-binding proteins may recognise palindromes.pal·in·drome (pal'in-drōm) molecular biology A self-complementary nucleic acid sequence; a sequence identical to its complementary strand, if both are "read" in the same 5'-3' direction, or inverted repeating sequences running in opposite directions (but same 5'- to 3'- direction) on either side of an axis of symmetry; palindromes occur at sites of important reactions. [G. palindromos, a running backward] Fig. 243 Palindrome . palindrome a sequence in double-stranded nucleic acids that reads the same on both strands when reading one strand from left to right and the other from right to left (i.e. both strands are read 5′ → 3′). See Fig. 243 .In a single-stranded molecule, COMPLEMENTARY BASE PAIRING can occur when the chain is folded back (See also HAIRPIN). Palindromes occur in, for example, many operator sequences (see OPERON MODEL), transcription terminator sequences (see TRANSCRIPTION).and most recognition sites for RESTRICTION ENZYMES.palindrome
