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′)

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.

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.

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.

THE SHORT STORY OF UKRAINIAN PALINDROME

Second, palindromists who strive for coherence, clarity and naturalness of language in their compositions are confronted by the prosaic fact that most "natural" language, and especially spoken language, consists largely of palindromically unexciting short words.

If his results too often seem only a caricature of poetry, blame it on the considerable logological constraints under which he toiled and not on his muse, for not even the most adept of palindromists can be expected simply to neutralize, somehow, those expression-impeding limitations.

Haiku Palindromes

Palindromists attempt to mold a palindrome to the complex contours of some rhymed poetical form chiefly for the sake of the mental challenge the problem presents and the satisfaction to be found in solving it, and not primarily, as with other poetry, to share with others the poet's ideas or impressions.
