Final answer:

DNA has two strands with complementary base-pairing rules that maintain its structure and function, forming the iconic double helix as proposed by Watson and Crick.


Explanation:

DNA has two strands in anti-parallel orientation. The sugar-phosphate linkages form a backbone on the outside, and the bases are paired on the inside: A with T, and G with C, like rungs on a spiral ladder.

The complementary base-pairing rules in DNA are crucial for its structure and function. These rules ensure that adenine always pairs with thymine, and guanine with cytosine, maintaining the stability of the DNA molecule.

The double helix structure of DNA, as proposed by Watson and Crick, showcases the intricate bonding between nucleotide bases that allows DNA to store and transmit genetic information accurately.
