Answer:
One of the strands is inverted. Both the strands are anti-parallel to each other.
Step-by-step explanation:
Deoxyribonucleic acid (DNA) is a double helix structure made up of two strands. Both the strands remain intact due to the hydrogen bonding present in them.
Both the strands are anti-parallel to each other. One strand runs in the 5'-3' direction and is known as the leading strand. The other strand runs in 3'-5' direction and is known as the lagging strand. Hence, both the strands have an opposite orientation.
