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 meaning of palindrome in the context of genetics is slightly different, from the definition used for words and sentences. Since the DNA is formed by two paired strands of nucleotides , and the nucleotides always pair in the same way ( Adenine (A) with Thymine (T), Cytosine (C) with Guanine (G)), a (single-stranded) sequence of DNA is said ...
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]
A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16361) that remains the same when its digits are reversed. In other words, it has reflectional symmetry across a vertical axis.
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.
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.

For example, the internal palindrome sequence can be 4 to 8 base pairs in length and vary in the order of bases, however the pattern, 5'-Pu Pu CG Pu Py CG Py Py-3', was found to be the most active when compared to several other sequences. The poly G tail found at either end of the DNA strand can vary in length and even number (Type D only have ...
