Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of DNA sequence below would be a palindromic sequence?
A
AGCGCT
B
AGCAGC
C
AAAGGG
D
ACACAC
Explanation: 

Detailed explanation-1: -So the correct answer is ‘ 5’-GACCAG-3’ in one strand’.

Detailed explanation-2: -Moreover, CTAG is remark-ably underrepresented relative to its reverse palindromic sequence GATC. To determine the origin of compositional biases, we analyze structural features of palindromic DNA duplexes derived in all-atom molecular simula-tions.

Detailed explanation-3: -For a nucleotide sequence to be considered as a palindrome, its complementary strand must read the same in the opposite direction [2]. For example, the sequence 5’-CGATCG-3’ is considered a palindrome since its reverse complement 3’-GCTAGC-5’ reads the same. Palindromes can be exact or approximate.

Detailed explanation-4: -So, the correct answer is ‘3’-CTTAAG-5’.
