Watson and Crick.
Using cardboard cutouts they recognized the helical shape of DNA and the complimentary base pairing rule. That base A pairs with T and Base C pairs with G. They used information from Rosalind Franklin (who determined the width of DNA and the helical shape) and Chargoff (who discovered the equality rule). The structure of this model developed by Watson and Crick suggested a replication mechanism.
Hope this helps!
What else can I help you with?
What is a single, long molecule of DNA made of?
A single, long molecule of DNA is made up of a sequence of nucleotides, which are the building blocks of DNA.
How many DNA molecule in a chromatid?
Each chromosome is originally made of one DNA molecule.
Who were the scientist that developed the double helix model of DNA molecule?
James Watson and Francis Crick are the scientists credited with developing the double helix model of the DNA molecule in 1953. Their model revolutionized our understanding of how genetic information is stored and replicated in living organisms.
What makes up the sides of a DNA molecule?
A DNA molecule consists of two strands that are made up of sugar (deoxyribose) and phosphate molecules. The sides of the DNA molecule are formed by alternating sugar and phosphate molecules linked together to create a backbone for the molecule.
The backbone of the DNA molecule is made of what?
The backbone of the DNA molecule is made of alternating sugar (deoxyribose) and phosphate molecules. These sugar-phosphate chains are connected by covalent bonds.
What makes a working model of the DNA molecule?
protein
A model of a DNA molecule contains what?
Working as a model is a genuine employment
What is a single, long molecule of DNA made of?

How does a model of DNA differ from an actual DNA molecule?
A model of DNA is a representation, often simplified, of the double helix structure with the base pairs adenine, thymine, cytosine, and guanine. An actual DNA molecule is a complex biological entity made up of these base pairs that carries genetic information and can replicate and transcribe to produce proteins. Models may not capture all the intricacies and functions of a real DNA molecule.
How did Watson and Crick's model of the DNA molecule explain base pairing?
Watson and Crick's model of the DNA molecule showed that the double helix structure allowed for complementary base pairing between adenine and thymine, and between guanine and cytosine. This explained how DNA strands could replicate and pass on genetic information accurately.
