Detailed explanation-1: -Explanation: Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole). DNA (Deoxyribonucleic Acid) is composed of two polynucleotide strands (the polymers of nucleotides), which forms what looks like a ladder.
Detailed explanation-2: -In biochemistry, two biopolymers are antiparallel if they run parallel to each other but with opposite directionality (alignments). An example is the two complementary strands of a DNA double helix, which run in opposite directions alongside each other.
Detailed explanation-3: -In a DNA double helix, the strands run in opposite directions to permit base pairing between them, which is essential for replication or transcription of the encoded information.
