What Type of Symmetry is Created by Inverted Repeats in Double-Stranded

Question

What type of symmetry is created by inverted repeats in double-stranded DNA?
A) two-fold rotational
B) three-fold rotational
C) mirror plane
D) line
E) inversion center

Accepted Answer

Two-fold rotational symmetry is created by inverted repeats in double-stranded DNA, where the sequence on one strand is a reverse complement of the sequence on the opposite strand, allowing the molecule to be rotated 180 degrees and still align with itself.
