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.
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 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.
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.
What rule is used to join the free nucleotides to the exposed bases of the DNA?
The rule used to join free nucleotides to the exposed bases of DNA is base pairing. Adenine pairs with thymine, and guanine pairs with cytosine through hydrogen bonding. This complementary base pairing ensures the accurate replication of DNA during cell division.
What is the rule to join the free nucleotides to the exposed bases of the DNA?
watson-base pairing
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 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).
How did watson and cricks model of dna molecule explain base pairing?
well the dna molecule model was compared to Franklins
How does Watson-Crick base pairing contribute to the stability of the DNA double helix structure?

This specific pairing allows for the formation of a stable double helix structure, which is essential for the integrity and function of DNA.
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
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.

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.
