too silly
Their first model had 3 strands.
well the dna molecule model was compared to Franklins
Watson and Crick's model of DNA structure, the double helix, provided a physical explanation for Chargaff's rules by showing how the complementary base pairing of adenine-thymine and guanine-cytosine could fit within the double helix structure. This pairing resulted in equal amounts of A and T, and G and C, in a DNA molecule, which aligned with Chargaff's observation that the amounts of adenine and thymine, and guanine and cytosine, were nearly equal in DNA samples.
James Watson and Francis Crick are credited with building the first three-dimensional model of DNA in 1953, based on data collected by Rosalind Franklin and Maurice Wilkins. Their model proposed the double helix structure of DNA that has since become widely accepted.
Watson & Crick constructed the very first model of DNA :) is that what you were looking for ?
Watson and Crick's model of DNA showed a double helix.

Watson and Crick's ball and stick model of DNA best illustrates the double helix structure of DNA, where two strands of nucleotides are wound around each other. This model also shows the complementary base pairing between adenine and thymine, as well as between guanine and cytosine in the DNA molecule.
Three events that led to understanding the structure of DNA are: Chargaff's Rules, Franklin's Discovery, and Watson and Crick's Model.

Rosalind Franklin laughed at Watson and Crick's first model of DNA because it inaccurately represented the structure of the molecule. Their model did not incorporate key data from her X-ray diffraction images, particularly the crucial helical formation of DNA. Franklin recognized that their model was oversimplified and failed to account for the complexities of DNA's actual structure. Her laughter reflected her frustration with the lack of scientific rigor in their approach.
Watson and Crick's model of DNA, proposed in 1953, revealed the double helix structure of the DNA molecule. This model illustrated that DNA is composed of two intertwined strands, with a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, cytosine, and guanine) paired specifically (A with T and C with G) in the center. Their discovery provided a mechanism for genetic replication and laid the groundwork for understanding how genetic information is stored and transmitted in living organisms.
