Definition of Palindrome

Palindrome: In genetics, a DNA or RNA sequence that reads the same in both directions. The sites of many restriction enzymes that cut (restrict) DNA are palindromes.

In rheumatology, palindromic rheumatism is a form of joint inflammation in which the joints involved by the arthritis appear to change periodically from one region of the body to another and back again.

In general usage, a palindrome is a word (such as the name "Eve"), phrase, sentence (such as "Madam I'm Adam"), or number (such as 2002) that reads the same in both directions, backward or forward.
