They pair by hydrogen bonds holding them together. Covalent bonds hold the nucleotides together, creating a sugar-phosphate backbone.

Which bases always pair on DNA?
Adenine pairs with thymine and guanine pairs with cytosine
What base will always pair with another base?
A purine will always pair with a pyrimidine. Examples of purines are adenine (pairs with thymine or uracil) and guanine (pairs with cytosine). Examples of pyrimidines are thymine (pairs with adenine), uracil (pairs with adenine), and cytosine (pairs with guanine).
Which nitrogen bases can pair up together in DNA?
Adenine always pairs with Thymine, and Guanine always pairs with Cytosine. A with T, C with G.
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
What is the base unit of a nucleic acid?
The nitrogenous base units of a nucleic acid are Adenine, Cytosine, Guanine, and Thymine. (in Dna) in RNA Thymine is replaced with Uracil. These base pair are often abreviated to A,C,T,G, and U. Adenine will always pair with Thymine. Cytosine will always pair with guanine.
Which bases always pair on DNA?
Adenine pairs with thymine and guanine pairs with cytosine
What are the DNA base pairing rules?
Adenine always pairs with thymine Cytosine always pairs with guanine.
What nitrogen base always pairs up with adenine?
adenine with thymine cytosine with guanine adenine with uracil cytosine with guanine
What base will always pair with another base?

Which nitrogen bases can pair up together in DNA?
Adenine always pairs with Thymine, and Guanine always pairs with Cytosine. A with T, C with G.
Does the base Guanine always pair to Adenine?
In transfer RNA, yes, unless there is a mutation.
What base pairing arrangement is found in double-stranded DNA?
Adenine is paired with thymine.Cytosine is paired with guanine.
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 many rings do adenine and guanine have?
Adenine and guanine molecules are two of the four nitrogenous bases that help make up the structure of DNA. They are also known as "purine" bases because they have a double ring structure. The purine bases are extremely important in DNA formation and they specifically pair up with the other two nitrogenous bases, known as the "pyrimidine" bases. Adenine molecules will always pair with thymine molecules and guanine molecules will always pair with cytosine.
What are the 4 bases of the DNA ladder?
Adenine,Thymine,Guanine,and Cytosine. Adenine and thymine pair up and guanine and cytosine pair up.
Does cytosine pair with an adenine or a guanine base?
Cytosine binds [bonds] with Guanine.
What is the base unit of a nucleic acid?
The nitrogenous base units of a nucleic acid are Adenine, Cytosine, Guanine, and Thymine. (in Dna) in RNA Thymine is replaced with Uracil. These base pair are often abreviated to A,C,T,G, and U. Adenine will always pair with Thymine. Cytosine will always pair with guanine.
