Watson and Crick postulated that the DNA molecule consists of two strands that are complementary and that adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G) through hydrogen bonding. This base pairing rule is known as Chargaff's rules and is fundamental to the structure of DNA.

How does Watson-Crick base pairing contribute to the stability of the DNA double helix structure?
Watson-Crick base pairing contributes to the stability of the DNA double helix structure by ensuring complementary pairing of nucleotide bases. Adenine pairs with thymine and guanine pairs with cytosine, forming hydrogen bonds that hold the two strands together. This specific pairing allows for the formation of a stable double helix structure, which is essential for the integrity and function of DNA.
What is the error in Watson-Crick DNA model paper?
The 1953 Nature paper by James Watson and Francis Crick stated that each base pair (purine-pyrimidine pair, A-T and C-G) was held together by two hydrogen bonds.It is now established that, while this is true for adenine-thymine (A-T), the cytosine-guanine (C-G) pairing involves three hydrogen bonds.For a reproduction of the original paper, see:http://www.nature.com/nature/dna50/archive.html
How Didi Watson and Crick's model of the DNA molecule explain base pairing?
Watson and Crick's model of the DNA molecule proposed a double helix structure where complementary bases pair up (A with T, G with C) through hydrogen bonding. This base pairing allows for specific and stable interactions between the bases, facilitating accurate DNA replication and information transfer.
What did Watson need to consider when he worked out the DNA base pairing?
Watson needed to consider the complementary nature of DNA base pairs (A pairs with T, and G pairs with C), the stability of hydrogen bonding between the bases, and the size constraints of fitting the bases within the double helix structure of DNA.
Information from X-ray crystallographic data collected by was used by Watson and Crick in their development of the model of DNA?
Yes, Watson and Crick used the X-ray diffraction images of DNA taken by Rosalind Franklin and Maurice Wilkins to propose the double-helix model of DNA structure in 1953. This data provided crucial insights into the helical nature of DNA and the specific pairing of its nucleotide bases.
What is the rule to join the free nucleotides to the exposed bases of the DNA?

How did watson and cricks model of dna molecule explain base pairing?
well the dna molecule model was compared to Franklins
In the Watson-Crick model of a double helix the steps of the spiral staircase are composed of?
In the Watson-Crick model of a double helix, the steps of the spiral staircase are composed of nitrogenous bases. These bases include adenine (A) pairing with thymine (T) and cytosine (C) pairing with guanine (G) through hydrogen bonds.
How did chargaffs rules helped Watson and crick model DNA?
Chargaff’s rules provided Watson and Crick with crucial information about the base pairing in DNA: adenine pairs with thymine and guanine pairs with cytosine in equal amounts. This information helped them to propose the double helix structure of DNA, with complementary base pairing along the strands.
How is complementary base pairing different when pairing DNA to DNA than pairing DNA to mrna?
Complementary base pairing in DNA-DNA pairing involves adenine (A) pairing with thymine (T) and cytosine (C) with guanine (G), following the rules of Watson-Crick base pairing. In DNA-mRNA pairing, uracil (U) replaces thymine, so adenine (A) pairs with uracil (U) in mRNA instead of thymine (T).
What is an example of the base pairing rule within Watson crick double helix model of DNA?
A is always with T and C is always with G
What scientist are credited with base pairing rules?
James Watson and Francis Crick are credited with the base pairing rules and DNA structure in general. Erwin Chargaff is credited with the rules of base pairs in that the number of pyrimidines is equal to the number of purines.

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.
