DNA contains thymine instead of uracil to maintain stability and integrity of genetic information. Uracil can form base pairs with adenine, but its presence in DNA would complicate the repair processes, as uracil can arise from cytosine deamination. Thymine, with its methyl group, provides a distinction that helps the DNA repair machinery recognize and fix mutations more effectively. Thus, the use of thymine enhances the overall fidelity of the genetic material.
What else can I help you with?
What is a pyrimidine not found in DNA?
Uracil is a pyrimidine base that is not found in DNA. Instead, uracil is found in RNA, where it pairs with adenine, unlike DNA where thymine pairs with adenine.
What bases are found in DNA?
Adenine, Thymine, Guanine, and Cytosine
Is it DNA if nucleic acid contains uracil?
If you are inquiring about the decontamination of nucleic acid amplification reactions USING uracil (UDG), you should find this article interesting... http://www.patentstorm.us/patents/5536649/description.html Very compelling. * A nucleic acid that contains uracil must be RNA, not DNA.
What does Adenine A bond with?
Adenine bonds with thymine in DNA and uracil in RNA.
DOES DNA HAVE URACIL AS A BASE?
No, DNA does not contain uracil as a base. Instead, DNA uses thymine as one of its four nucleotide bases, alongside adenine, cytosine, and guanine. Uracil is found in RNA, where it replaces thymine and pairs with adenine during RNA synthesis.
Is uracil always paired with adenine in double-stranded DNA?
No, 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.
3 DNA does NOT contain the nitrogen base?
DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil
What nitrogenous bases are not found is DNA?
Uracil is a nitrogenous base that is not found in DNA. DNA instead contains the bases adenine, guanine, cytosine, and thymine. Uracil is found in RNA.
What is a pyrimidine not found in DNA?
Uracil is a pyrimidine base that is not found in DNA. Instead, uracil is found in RNA, where it pairs with adenine, unlike DNA where thymine pairs with adenine.
What bases are found in DNA?
Adenine, Thymine, Guanine, and Cytosine

What nuclictide is replaced in RNA?
In RNA, thymine (T) is replaced by uracil (U). This means that RNA contains adenine (A), cytosine (C), guanine (G), and uracil (U) nucleotides, while DNA contains adenine (A), cytosine (C), guanine (G), and thymine (T) nucleotides.
What is the base that is found in RNA but not in DNA?
Thymine
Does RNA contain the nitrogen base uracil?
NO. RNA contains URACIL while in DNA it is THYMINE, the uracil replaces the thymine.
What is the nitrogenous bases in RNA differ from those in DNA?
Three bases are identical in both DNA and RNA: adenine (A), cytosine (C), and guanine (G). The fourth base in RNA is uracil (U); in DNA it is thymine (T). The difference between these two is small: U lacks a methyl group. A and G are purines; C, T, and U are pyrimidines, which are smaller.
Does RNA contains uracil rather than thymine?
In RNA, uracil is substitued for thymine. In DNA, there is no uracil present. Thymine pairs with Adenine, and Cytosine pairs with Guanine. Uracil is ONLY in RNA. Never will uracil be in DNA. Chemically, uracil only differers from thymine in that it does not have a methyl group attached to C5, but only a hydrogen. Hope this helps!
What base is not present in the nucleotides of RNA?
RNA has the base uracil rather than thymine that is present in DNA, so the answer to you question is.. thymine.
