Uracil has a single aromatic ring in its structure. It is a pyrimidine derivative, which consists of a six-membered ring containing two nitrogen atoms and four carbon atoms. This simple structure is part of RNA, where uracil replaces thymine found in DNA.

What is the base of RNA in place of thymine which bonds with adenine?

The nitrogen base uracil takes the place of thymine in RNA. So in RNA, uracil pairs with adenine.


What are the four nitrogen bases of RNA?

Adenine, Uracil, Cytosine and Guanine; (adenine bonds with uracil) and (cytosine bonds with guanine). Thymine DOES NOT appear in the sequence; for instance if the DNA strand starts: A G C T, the Rna would be: A --> U G --> C C --> G T --> A.


What nucleotide replaces thymine?

Uracil replaces Thymine in DNA. Adenine and Thymine go together while Cytosine and Guanine go with each other in DNA. But, in RNA, Thymine is replaces with Uracil. So not Adenine and Uracil go together, while Cytosine and Guanine pair up.


What is in RNA but not in DNA?

Uracil


What does uracil pair with in the genetic code?

Uracil replaces thymine in RNA so uracil bonds with adenosine


What nitrogen base replaces thymine (T) in RNA?

RNA and DNA both share the nitrogen bases adenine (A), cytosine (C), and guanine (G).


Is uracil a DNA or a NA?

Uracil is a base in RNA


Is DNA composed of uracil?

No, only RNA contains uracil.


What does uracil replace in RNA?

Uracil replaces thymine in RNA.


Does RNA contain uracil?

Yes, RNA contains uracil.


Does trna contain uracil?

Yes, tRNA (transfer RNA) contains uracil. In the structure of tRNA, uracil replaces thymine, which is found in DNA. This presence of uracil is part of what distinguishes RNA from DNA, as RNA typically contains uracil instead of thymine.


Adenine complements with what in DNA RNA?

In DNA: Adenine base pairs with Thyamine A=T In RNA: Adenine base pairs with Uracil A=U
