| Palfyn's sinus | A space within the crista galli of the ethmoid described as communicating with the ethmoidal and frontal sinus's. Paranasal sinuses, the paired air-filled cavities in the bones of the face lined by mucous membrane continuous with that of the nasal cavity; these sinus's are the frontal, sphenoidal, maxillary, and ethmoidal. Synonym: sinus paranasales. (05 Mar 2000) |

| palindrome | <molecular biology> A word or sentence that reads the same backwards as it does forward, such as radar. A nucleic acid sequence whose 5'-to-3' sequence is identical on each DNA strand. The sequence is the same when one strand is read left to right and the other strand is read right to left. Recognition sites of many restriction enzymes are palindromic. (09 Oct 1997) |
| palindrome in genetics | A palindrome is a word that reads the same in both directions as, for example, the names eve or anna. In genetics, a palindrome is a DNA or RNA sequence that reads the same in both directions. The sites of many restriction enzymes that cut (restrict) DNA are palindromes. Palindromic rheumatism is a form of joint inflammation whereby the joints involved appears to change periodically from one region of the body to another and back again. (12 Dec 1998) |

| palindromic sequence | <molecular biology> Nucleic acid sequence that is identical to its complementary strand when each is read in the correct direction (e.g. TGGCCA). Palindromic sequences are often the recognition sites for restriction enzymes. Degenerate palindromes with internal mismatching can lead to loops or hairpins being formed (as in tRNA).

| palingenesy | 1. A new birth; a re-creation; a regeneration; a continued existence in different manner or form. 2. <biology> That form of evolution in which the truly ancestral characters conserved by heredity are reproduced in development; original simple descent; distinguished from kenogenesis. Sometimes, in zoology, the abrupt metamorphosis of insects, crustaceans, etc. See Genesis. Origin: Gr.; again + birth: cf. F. Palingenesie. (07 May 1998) |
| palingenetic | Of or pertaining to palingenesis: as, a palingenetic process. (07 May 1998) |
