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 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 of dna molecule explain base pairing?
well the dna molecule model was compared to Franklins
How did Watson and Crick determine the three-dimensional shape of DNA?
Watson and Crick determined the three-dimensional shape of DNA through model-building and analysis of X-ray diffraction images captured by Rosalind Franklin. Their model of the double helix structure of DNA was based on the complementary base pairing of adenine-thymine and guanine-cytosine, as well as the sugar-phosphate backbone.
When two strands of DNA line up a adenine always pairs up with?
Uracil in Watson-Crick base-pairing though non-standard pairs exist.
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.
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.
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 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.
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.
What methods did Crick and Watson use to determine the structure of DNA?
Crick and Watson determined the structure of DNA using X-ray crystallography data collected by Rosalind Franklin. They also built physical models and used trial and error to discover the double helix structure of DNA, with the help of base pairing rules proposed by Erwin Chargaff.
Why did Watson and Crick conclude that each base could not pair with itself?
Watson and Crick concluded that each base could not pair with itself based on the complementary base pairing rules in DNA. Specifically, they found that adenine paired with thymine and guanine paired with cytosine. This complementary base pairing allows for the precise replication of genetic information during DNA replication.
How did chargaffs rules helped Watson and crick model?
Chargaff's rules provided key information about the base composition of DNA, which guided Watson and Crick's understanding of the structure of DNA. Specifically, Chargaff's rules stated that the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine. This information was crucial in helping Watson and Crick establish the complementary base pairing necessary for the double helix structure of DNA.

well the dna molecule model was compared to Franklins
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 did Watson and Crick determine the three-dimensional shape of DNA?
Watson and Crick determined the three-dimensional shape of DNA through model-building and analysis of X-ray diffraction images captured by Rosalind Franklin. Their model of the double helix structure of DNA was based on the complementary base pairing of adenine-thymine and guanine-cytosine, as well as the sugar-phosphate backbone.
