Which DNA sequence forms a palindromic sequence?
A) 5ʹ-ACTGAG-3ʹ
B) 5ʹ-ACTATT-3ʹ
C) 5ʹ-ACTAGT-3ʹ
D) 5ʹ-ACTACT-3ʹ
E) 5ʹ-ACTTAT-3ʹ

Quizplus · Accepted Answer

A palindromic sequence is when the sequence of nucleotides is the same in both directions on a double-stranded DNA molecule. The sequence 5ʹ-ACTAGT-3ʹ reads the same in the opposite direction (3ʹ-TGATCA-5ʹ) when the complementary strand is formed.
