WebInverted repeat. An inverted repeat (or IR) is a single stranded sequence of nucleotides followed downstream by its reverse complement. [1] The intervening sequence of nucleotides between the initial sequence and the reverse complement can be any length including zero. For example, 5'---TTACGnnnnnnCGTAA---3' is an inverted repeat sequence. WebThe palindromic DNA or palindromes are the inverted repeats and region of dyad symmetry. The length of palindromes may be short by about 3-10 bases or long by about 50-100 base pairs. ... Consequently a palindrome produces an intrastrand double stranded structure which is known as hairpin (Fig 5.10 A).
