Detailed explanation-1: -DNA molecules have an antiparallel structure-that is, the two strands of the helix run in opposite directions of one another.
Detailed explanation-2: -The strands of a DNA double helix are said to be “antiparallel” because the have the same chemical structure, but are opposite in direction.
Detailed explanation-3: -DNA is composed of two strands of nucleotides held together by hydrogen bonding. The strands each run from 5’ to 3’ and run in antiparallel, or opposite, directions from one another.
Detailed explanation-4: -The chromosomes of many organisms are composed of two DNA strands: one strand is oriented in the 5′–3′ direction with respect to the carbon atoms on the sugar (deoxyribose) and the complimentary strand is in the opposite 3′–5′ direction.
Detailed explanation-5: -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.
