<em>One of the strands is inverted. Both the strands are anti-parallel to each other.</em>
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.
Covalent bonds are formed when two non metal atoms share an electron. The atoms either give up or gain an electron, due to the outer shell being unstable.
