Detailed explanation-1: -A palindromic sequence is a sequence made up of nucleic acids within double helix of DNA and/or RNA that is the same when read from 5’ to 3’ on one strand and 3’ to 5’ on the other, complementary, strand.
Detailed explanation-2: -What Is a DNA Palindrome? A palindromic sequence of nucleotides (which are labeled A, T, C, or G) occurs when complementary strands of DNA read the same in both directions, either from the 5-prime end or the 3-prime end.
Detailed explanation-3: -The palindromic sequences are the sequences of the nucleotides which reads same from either side, that is forward and backward. These are the sequences which are present on the DNA or RNA double helix.
Detailed explanation-4: -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.
Detailed explanation-5: -An inverted repeat (IR) occurs when two exact or approximate copies of a particular DNA sequence are present in reverse complement orientation. An IR is called a palindrome if the two copies directly abut each other, so their separation distance (here called the spacer length) is zero.
