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 nuclictide is replaced in RNA?

The four nucleotides in RNA are Adenine, Guanine, Cytosine, and Uracil. Uracil is not present in DNA which instead contains Thymine.


What bases are found in DNA?

Adenine, Thymine, Guanine, and Cytosine


Is guanine in DNA or RNA?

Both DNA and RNA contain guanine (G). DNA contains guanine (G) which pairs with cytosine (C), and adenine (A) which pairs with thymine (T). In RNA, T is replaced by uracil (U), so G pairs with C, and A pairs with U. Uracil is an unmethlyated form of thymine.


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.


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


What does Adenine A bond with?

Adenine bonds with thymine in DNA and uracil in RNA.


What nitrogenous base is found in DNA but not in RNA is called what?

The nitrogenous base found in DNA but not RNA is called thymine. RNA contains the base uracil which during transcription(when genetic information is copied from DNA to RNA) pairs with the base adenine in DNA. So, DNA has four nitrogenous bases: (A) adenine, (C) cytosine, G (guanine), and T (thymine). And RNA has four nitrogenous bases: (A) adenine, (C) cytosine, G (guanine) and U (uracil)


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 match with?

In DNA, adenine pairs with thymine. In RNA, adenine pairs with uracil.


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.
