Uracil
Uracil (U) is one of four chemical bases that are part of RNA. The other three bases are adenine (A), cytosine (C), and guanine (G). In DNA, the base thymine (T) is used in place of uracil.

Uracil-N-glycosylase
A repair enzyme that removes uracil from DNA by cleaving the bond between the base and the sugar backbone. This enzyme ensures that DNA contains T instead of U residues.

Uracil A nitrogenous base normally found in RNA but not DNA; uracil is capable of forming a base pair with adenine.

Uracil is one of the four bases in RNA. The others are adenine, cytosine, and guanine. Uracil replaces thymine, which is the fourth base in DNA. Like thymine, uracil always pairs with adenine. [Talking Glossary]

Uracil (U)
Uracil is a pyrimidine base (nitrogenous base) and constituent of nucleotides and as such one member of the base pair A-U (adenine-uracil). It is normally found in RNA but not DNA.

These hydrogen bonding modes are for classical Watson-Crick base pairing.

urban Peculiar to the human environment, as contrasted with that found normally around wild animals.
Members of the pairs adenine-thymine, adenine-uracil, and guaninecytosine that have the ability to hydrogen bond to one another. (See nucleotide.) Concatemer. A DNA segment composed of repeated sequences linked end to end. Conjugation.
Base sequence -- a partnership of organic bases found in DNA and RNA; adenine forms a base pair with thymine (or uracil) and guanine with cytosine in a double-stranded nucleic acid molecule.
RNA, however, substitutes the sugar ribose for deoxyribose and the base uracil for thymine, and is usually single-stranded. One form of RNA, messenger RNA or mRNA, conveys the DNA recipe for protein synthesis to the cell cytoplasm.
ribonucleic acid (RNA) Nucleic acid containing ribose sugar and the base Uracil; RNA functions in protein synthesis. The single starnded molecule transcribed from one strand of the DNA.
A subunit of DNA or RNA consisting of a nitrogenous base (purine in adenine and guanine, pyrimidine in thymine, or cytosine for DNA and uracil cytosine for RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA).
cytidine deaminases that convert a C in the RNA to uracil (U);
adenosine deaminases that convert an A to inosine (I), which the ribosome translates as a G. Thus a CAG codon (for Gln) can be converted to a CGG codon (for Arg).
(RNA, like DNA, is made up of nucleotides although t he nucleotide uracil (U) is used in place of thymine (T).) The RNA transcribed from a gene is called messenger RNA.

However, the nucleotides in RNA contain the sugar ribose instead of deoxyribose and they contain uracil instead of thymine. The RNA is synthesized from the "sense" strand of the DNA molecule.
Complementary nucleotides. Members of the pairs adenine-thymine, adenine-uracil, and guaninecytosine that have the ability to hydrogen bond to one another. (See nucleotide.) ...
A nitrogenous base, such as cytosine, thymine, or uracil, with a characteristic single-ring structure; one of the components of nucleic acids.
A single-stranded nucleic acid similar to DNA but having ribose sugar rather than deoxyribose sugar and uracil rather than thymine as one of the pyrimidine bases.
Also known as: ribonucleic acid ...
The bases in the mRNA strand are opposite (complimentary) to the bases in the DNA template strand; it resembles the sense strand of DNA except that the base thymine is replaced by uracil.
Nucleotide A building block of a nucleic acid consisting of a base (adenine, thymine, cytosine, guanine, uracil) joined to a sugar (ribose or deoxyribose) and a phosphate.
Null mutation A mutation which leads to the absence of a gene product.
PYRIMIDINE BASES - Cytosine (C), Thymine (T) or Uracil (U) (see NUCLEOTIDE).
Glycosylated base is cytidine, it's derived from pyrimidine. It is one of the four nitrogenous bases, including in dna adenine, thymine, and guanine, and in rna adenine, uracil, and guanine.
components of nucleotides (despite the basic nature of nucleotides, nucleic acids are acidic due to the phosphate atoms they contain). The five bases that form the nucleic acids are adenine (A), guanine (G), cytosine (C), tymine (T) and uracil (U).
