Detailed explanation-1: -Double Helix A DNA molecule is made up of two linked strands that wind around each other to resemble a twisted ladder in a helix-like shape. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
Detailed explanation-2: -Answer: The right answer to the given question is option A) A double helix. It best describes the structure of a DNA molecule. Moreover, the DNA is not a single stranded and it does not comprise amino acids.
Detailed explanation-3: -Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
Detailed explanation-4: -Option (d) The two strands having complementary base pairing have the same helical geometry but have opposite polarity. This is because the strands are held together are antiparallel in nature.
