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 else can I help you with?
What is best illlustrated by Watson and cricks ball and stick model of DNA?
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.
In the Nature article what base pairing rules did Watson and Crick postulate?
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 did the information from Rosalind Franklin's photo help Watson and crick determine how bases are paired?
Rosalind Franklin's X-ray diffraction image of DNA provided crucial information about the structure of DNA, including the helical shape and dimensions of the molecule. This data allowed Watson and Crick to deduce that DNA is a double helix composed of two antiparallel strands, with adenine pairing with thymine and guanine pairing with cytosine through hydrogen bonds. Franklin's photo essentially confirmed the complementary base pairing in DNA, which was essential for understanding how genetic information is stored and replicated.
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.
Describe how watson and crick discoverd the structure of dna?
Watson and Crick used X-ray crystallography data from Rosalind Franklin and Maurice Wilkins to propose the double helix structure of DNA in 1953. They built physical models of the DNA molecule and demonstrated how complementary base pairing allows for the transmission of genetic information. Their discovery revolutionized the field of molecular biology.
How did watson and cricks model of dna molecule explain base pairing?
well the dna molecule model was compared to Franklins
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.

How did Watson and cricks model explain the basis for chargaffs rules?
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.
