Hint: In DNA, the opposite strands contain complementary bases. In a double-stranded DNA, one strand runs in the \[5' \to 3'\] direction while the other runs in \[3' \to 5'\]i.e. the reverse direction.
Complete answer: DNA forms a double helix and nucleotides form the structural base of it. DNA has two strands with complementary nitrogen bases.
One of these strands runs in \[3' \to 5'\]direction while the other runs in the reverse direction \[5' \to 3'\]. They run in opposite directions but remain parallel.
In other words, the two polynucleotide chains are antiparallel to each other.
Their nitrogen bases project inward; these are joined by hydrogen bonds.
So, the correct option is C. Antiparallel
Note: DNA is a nucleic acid chain composed of deoxyribose sugar.
Francis Crick, J.D. Watson along with Rosaline Franklin had prepared a three-dimensional DNA model.
The antiparallel strands of DNA twist around a common axis to form the complete three-dimensional DNA structure- the double helix. It is known as the staircase model.
