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).

How are the two strands of the double helix held together?
by the sugars - adenine , thymine , cytosine, and guanine
What two bases are in purines?
Adenine and guanine are the two purines bases present in DNA.Two purines in DNA are adenine and guanine.
How many bonds hold the bases of C and G together?
Adenine and Thymine Guanine and Cytosine held together by hydrogen bonds: 2 for A-T and 3 for G-C
What are the nitrogen bases found in RNA and what do they bond to?
Adenine and Uracil, which pair together (Uracil takes the place of Thymine from DNA) Guanine and Cytosine, which also pair together
Which bases are complementary to one another how are they held together in the double helix of DNA?
Adenine binds to Thymine Guanine binds to Cytosine Hydrogen bonding holds the bases together.
Which is the strongest base pair?
Guanine and cytosine because they are held together by three hydrogen bonds while adenine and thymine are held together by 2.
How are the two strands of the double helix held together?
by the sugars - adenine , thymine , cytosine, and guanine
True or false The strands of a DNA molecule are held together by hydrogen bonding between adenine with guanine molecules and cytosine with thymine molecules?
False. Adenine pairs with thymine and guanine pairs with cytosine.
What two bases are in purines?
Adenine and guanine are the two purines bases present in DNA.Two purines in DNA are adenine and guanine.
What are the bondings is nitrogenous bases?
nitrogenous bases are held together with hydrogen bonds. adenine and thymine (or uracil) are held by 2 and guanine and cytosine are held by 3.
How many bonds hold the bases of C and G together?
Adenine and Thymine Guanine and Cytosine held together by hydrogen bonds: 2 for A-T and 3 for G-C
What are the base pairing rules of rna?
DNA: Adenine - Thymine Guanine - Cytosine RNA (URACIL REPLACES THYMINE!): Adenine - Uracil Guanine - Cytosine
What makes up the rungs of the ladder of DNA?
The nitrogenous bases Adenine, Thymine, Guanine, and Cytosine Adenine and Thymine are always together and Cytosine and Guanine are always together.
What are the nitrogen bases found in RNA and what do they bond to?
Adenine and Uracil, which pair together (Uracil takes the place of Thymine from DNA) Guanine and Cytosine, which also pair together
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 the 4 different bases in DNA?
A-Adenine C-Cytosine T-thymine G-guanine
What nitrogen base always pairs up with adenine?
adenine with thymine cytosine with guanine adenine with uracil cytosine with guanine
