Final answer:
When viewing a right-handed DNA double helix along the central axis with the spirals twisting away, the spirals would twist in a clockwise direction, and the structure is composed of two anti-parallel strands held together by base pairing.
Step-by-step explanation:
When you look along the central axis of a right-handed DNA double-helix with the spirals twisting away from you, the spirals would twist in a clockwise direction. This right-handed helical structure of DNA consists of two strands wound around each other, resembling a spiral staircase. The structure is stabilized by hydrogen bonds between pairs of nitrogenous bases: adenine pairs with thymine, and guanine pairs with cytosine. The two strands are anti-parallel; this means the 3' end of one strand is opposite the 5' end of the other strand, which is essential for the specificity of base pairing and the overall stability of the helix.
