What are the rungs made of in a double helix DNA?
The 'rungs' in DNA consist of adenine, thymine, cytosine, and guanine. Adenine and thymine bond, and cytosine and guanine bond.
What molecule binds adenine with thymine and cytosine with guanine?
Adenine: C5N5H5 Cytosine: C4H5N3O Guanine: C5H5ON5 Thymine: C5H6N2O2 Uracil : C4H4N2O2
What is adenine and guanine held together with?
The Cytosine, Guanine, Adenine and Thymine bases present in DNA are molecules that are held together by intermolecular hydrogen bonds. This bond occurs between an electronegative atom (known as a hydrogen bond acceptor) and a hydrogen atom attached to another electronegative atom (known as a hydrogen bond donor).
Why does C always have to bond with G?
C always has to bond with G because of base pairing rules. Only between Cytosine and Guanine are there opportunities to form hydrogen bonds. This is why Adenine or Thymine cannot bond with Guanine and Cytosine.
What are cytosine and guanine?
cytosine and thymine are pyrimidine bases, and adenine and quanine are purine bases:)). YOUR WELCOME!!

What holdes nitrogen bases together?
A weak hydrogen bond, adenine and thymine have a double hydrogen bond cytosine and guanine have a triple hydrogen bond
What molecule binds adenine with thymine and cytosine with guanine?
Adenine: C5N5H5 Cytosine: C4H5N3O Guanine: C5H5ON5 Thymine: C5H6N2O2 Uracil : C4H4N2O2
What bases match up with which for DNA?
Adenine pairs with Thymine(double hydrogen bond) and Guanine pairs with Cytosine(triple hydrogen bond). (A)-(T) (G)-(C)
In DNA adenine pairs with?
Short answer: Adenine More information: In the model of DNA that was discovered by Rosalind Franklin, James Watson and Francis Crick in 1953 proposed that DNA was a double helix structure with 4 bases which pair to each other. Due to experiments that had been carried out by other scientists at the time (namely Erwin Chargoff in 1949) he showed that despite the amount of DNA present the amount of adenine was always equal to the amount of thymine and the amount of cytosine to the amount of guanine. When Watson had this information he suddenly realised that the adenine-thymine bond was the same length as the cytosine-guanine bond and therefore they would pair to each other in a double helix model. Thymine and adenine are held together by a double hydrogen bond; whereas cytosine and guanine form a triple hydrogen bond.

Thymine adenine guanine and cytosine are?
Thymine,adenine,guanine and cytosine are nucleotides.These nitrogen bases are the basic unit of life.These are called purine and pyrimidines.Adenine and thymine are paired by two hydrogen bond but guanine and cytosine by three hydrogen bond.
Bond which base pairs are linked in DNA?
They are linked by hydrogen bonds. Adenine and thymine have two hydrogen bonds while cytosine and guanine have three hydrogen bonds.
Why does C always have to bond with G?
C always has to bond with G because of base pairing rules. Only between Cytosine and Guanine are there opportunities to form hydrogen bonds. This is why Adenine or Thymine cannot bond with Guanine and Cytosine.
How do bases bond together?
Note that adenine only bonds with thymine, and cytosine only bonds with guanine. The nitrogen bases are held together by hydrogen bonds: adenine and thymine form two hydrogen bonds; cytosine and guanine form three hydrogen bonds.
What are cytosine and guanine?
cytosine and thymine are pyrimidine bases, and adenine and quanine are purine bases:)). YOUR WELCOME!!
Which nitrogen base bonds with adenine?
Thymine will always bond with adenine, and guanine will always bind with cytosine.
