Some kinds of atoms that are found in DNA must be left out of the models
Limitation enzymes are crucial in DNA recombinant technology because they can precisely cut DNA at specific sequences, allowing for the removal or insertion of genes. This enables the creation of recombinant DNA molecules with desired genetic information. Limitation enzymes play a key role in gene cloning, gene editing, and other biotechnological applications.
A key limitation of DNA polymerase is that it can only add nucleotides to an existing strand of DNA; it cannot initiate the synthesis of a new strand from scratch. This means that a primer, typically made of RNA, must be present for DNA polymerase to start DNA synthesis. Additionally, DNA polymerase has a proofreading function, but it can still make errors during replication, leading to potential mutations.
Rosalind Franklin made an X-ray crystallography showing a DNA molecule. Then, Watson and Crick used hers to create their own model using DNA's structure. Their model is still correct today and many people use it and look at it for reference.
Watson & Crick constructed the very first model of DNA :) is that what you were looking for ?
So there.

James Watson and Francis Crick are the scientists credited with discovering the three-dimensional structure of DNA using a model made of metal and wood in 1953. Their model revealed the double helix structure of DNA, which has since become a fundamental concept in biology and genetics.

the first dna model was made in 1953 by james watson
When was the first DNA
A tool called a DNA model or a DNA double helix model is used to show the structure of DNA. These models typically depict the double-stranded helical structure of DNA, showing the sugar-phosphate backbone and the nitrogenous bases paired in the center.
