A: Palindrome, B: Loop, C: Stem. A palindromic sequence is a nucleic acid sequence in a double-stranded DNA or RNA molecule whereby reading in a certain direction (e.g. 5' to 3') on one strand is identical to the sequence in the same direction (e.g. 5' to 3') on the complementary strand. This definition of palindrome thus depends on ...
For example, the common restriction enzyme EcoRI recognizes the palindromic sequence GAATTC and cuts between the G and the A on both the top and bottom strands. This leaves an overhang (an end-portion of a DNA strand with no attached complement) known as a sticky end [2] on each end of AATT.
The intervening sequence of nucleotides between the initial sequence and the reverse complement can be any length including zero. For example, 5'---TTACGnnnnnn CGTAA---3' is an inverted repeat sequence. When the intervening length is zero, the composite sequence is a palindromic sequence. [2]

For example, there are two PstI recognition sites in the following DNA sequence fragment, starting at base 9 and 31 respectively. A recognition sequence is a specific sequence, usually very short (less than 10 bases). Depending on the degree of specificity of the protein, a DNA-binding protein can bind to more than one specific sequence.
In computer science a palindrome tree, also called an EerTree, [1] is a type of search tree, that allows for fast access to all palindromes contained in a string.They can be used to solve the longest palindromic substring, the k-factorization problem [2] (can a given string be divided into exactly k palindromes), palindromic length of a string [3] (what is the minimum number of palindromes ...
An asymmetric three allele STR locus that can be used to observe deletions and recombinational rearrangements in the palindromic region of the Y chromosome. 17-29 (many incomplete alleles) nomenclature: DYF401 DYF401 is a palindromic region marker. DYF406S1 11 DYF408 DYF408 is a palindromic region marker. DYF411 DYF411 is a palindromic region ...
Restriction enzymes are endonucleases from eubacteria and archaea that recognize a specific DNA sequence. [3] The nucleotide sequence recognized for cleavage by a restriction enzyme is called the restriction site. Typically, a restriction site will be a palindromic sequence about four to six nucleotides long. Most restriction endonucleases ...
