No nitrogen base is missing. You may be referring to the fact that DNA contains the nitrogen base thymine, while RNA contains the nitrogen base uracil. They both contain adenine, cytosine, and guanine.
RNA has the base uracil rather than thymine that is present in DNA, so the answer to you question is.. thymine.
In RNA, the nitrogenous base of U (Uracil) is in place of T (Thymine) in DNA.
DNA to RNA Cytosine to Guanine Guanine to Cytosine Adenine to Uracil Thymine to Adenine
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
Adenine pairs with thymine.
In RNA the base Uracil (U) replaces Thymine, this makes the bases for RNA A,C,G,U.
RNA has the base uracil which replaces the thymine base of DNA.
RNA has the base uracil which replaces the thymine base of DNA.
Uracil. Uracil replaces thymine in RNA.
Uracil replaces thymine in RNA.
RNA and DNA both share the nitrogen bases adenine (A), cytosine (C), and guanine (G).
The base "uracil" is not found in the structure of DNA, but rather in RNA, as uracil replaces thymine in RNA.
Uracil; it replaces DNA's thymine.
In DNA thymine is one of the nitrogen bases, but in RNA uracil replaces thymine still leaving four nitrogen bases
Uracil replaces thymine in RNA. Uracil is one of the four nitrogenous bases found in RNA, along with adenine, cytosine, and guanine.
Uracil is the nitrogen base found in RNA but not in DNA. It replaces thymine, which is found in DNA and not in RNA. Uracil forms base pairs with adenine in RNA during transcription and translation processes.
Uracil replaces thymine in RNA as one of the four nitrogenous bases. Uracil pairs with adenine through hydrogen bonding in RNA, similar to how thymine pairs with adenine in DNA.
