Cytosine is always coupled with Guanine. (I like to remember that the round letters stick together).
In DNA, Thymine is coupled with Adenine, but in RNA, Thymine is replaced by Uracil.
Therefore, in RNA, U and A go together, always.

∙ 11y agoNo, Uracil doesn't occur in double stranded DNA. Doublestranded DNA contains Guanine paired with Cytosine and Adenine paired with Thymine.
In RNA, however, Adenine is always paired with Uracil instead of Thymine.

∙ 12y agoNo, uracil is found in the molecule of RNA, not DNA.

∙ 10y agoNo never...cytosine always pairs with guanine!
A=T(double bond)
G=C(triple bond)

What are the DNA base pairing rules?
Adenine always pairs with thymine Cytosine always pairs with guanine.
Which bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
What are the base pairing rules of rna?
DNA: Adenine - Thymine Guanine - Cytosine RNA (URACIL REPLACES THYMINE!): Adenine - Uracil Guanine - Cytosine
What nitrogen base always pairs up with adenine?
adenine with thymine cytosine with guanine adenine with uracil cytosine with guanine
What bases is found on RNA but not on DNA?
Like DNA, RNA contains the bases adenine (A), cytosine (C), and guanine (G); however, RNA does notcontain thymine, instead, RNA's fourth nucleotide is the base uracil (U). Unlike the double-stranded DNAmolecule, RNA is a single-stranded molecule.
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 are the DNA base pairing rules?
Adenine always pairs with thymine Cytosine always pairs with guanine.
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 bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
What are the base pairing rules of rna?
DNA: Adenine - Thymine Guanine - Cytosine RNA (URACIL REPLACES THYMINE!): Adenine - Uracil Guanine - Cytosine
What is the rule of pairs for DNA?
Chargaff's rule states: Adenine will always pair with Thymine in DNA; Guanine will always pair with Cytosine in DNA. Note: In RNA, no thymine is present, and its replaced by uracil; therefore, in RNA, Adenine pairs with Uracil.
What nitrogen base always pairs up with adenine?
adenine with thymine cytosine with guanine adenine with uracil cytosine with guanine
What bases is found on RNA but not on DNA?
Like DNA, RNA contains the bases adenine (A), cytosine (C), and guanine (G); however, RNA does notcontain thymine, instead, RNA's fourth nucleotide is the base uracil (U). Unlike the double-stranded DNAmolecule, RNA is a single-stranded molecule.
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.
What are the nitrogen based pairs?
The nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. They pair with each other as follows: adenine pairs with thymine, and cytosine pairs with guanine. The nitrogen bases in RNA are adenine, guanine, cytosine, and uracil. They pair with each other as follows: adenine pairs with uracil, and cytosine pairs with guanine.
What is the base pair rule for DNA?
In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.
What are the nitrogen bases in RNA and what binds to what?
they are adenine, guanine, cytosine and uracil (in place of thiamine) adenine binds with uracil and vice versa (with two hydrogen bonds) guanine bind with cytosine and vice versa (with three hydrogen bonds)
