True. Two antiparallel chains of polynucleotides make up a DNA molecule. Nucleotides are linked to one another all along sugar-phosphate backbone to form each strand. OH Sugar CH2 CH 3'end 5' end 5 end 3 end.
When two biopolymers run parallel to one another but in the opposite direction, they are said to be antiparallel in biochemistry. The complementary threads of a double helix of DNA which run in opposition to one another and are one example. A Dna has two antiparallel strands. The high degree of stability attained in an antiparallel arrangement is the primary cause of DNA strand antiparallelity. DNA is also capable of existing in a parallel configuration, but the base pairing (reverse Watson & Crick base pairing) will be different and the stability will be lower. if their alignments are different and they are parallel to one another. The two complimentary threads of a Dna helix, that run in opposition to one another, serve as an illustration.
