Detailed explanation-1: -Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.
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: -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-4: -The secondary structure of DNA is actually very similar to the secondary structure of proteins. The protein single alpha helix structure held together by hydrogen bonds was discovered with the aid of X-ray diffraction studies.
