Palindrome of DNA structure 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 ...
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]

Repeated sequences (also known as repetitive elements, repeating units or repeats) are short or long patterns that occur in multiple copies throughout the genome.In many organisms, a significant fraction of the genomic DNA is repetitive, with over two-thirds of the sequence consisting of repetitive elements in humans. [1]
These are known as palindromic (P) nucleotides due to the palindromic nature of the sequence produced when DNA repair enzymes resolve the overhang. [18] The process of hairpin opening by Artemis is a crucial step of V(D)J recombination and is defective in the severe combined immunodeficiency (scid) mouse model .
The presences of a poly G sequence at the 5' end, the 3' end, or both; An internal palindrome sequence; GC dinucleotides contained within the internal palindrome; A partially PS-modified backbone; Class A ODN typically contain 7 to 10 PS-modified bases at one or both ends that resist degradation by nucleases and increase the longevity of the ODN.
Placement of Cre under control of such a promoter results in localized, tissue-specific expression. As an example, Leone et al. have placed the transcription unit under the control of the regulatory sequences of the myelin proteolipid protein (PLP) gene, leading to induced removal of targeted gene sequences in oligodendrocytes and Schwann cells ...
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.
