When constructing the dna molecule what did you notice about the the orientation if the two strnads

One of the strands is inverted. Both the strands are anti-parallel to each other.

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.
