W2Q2 DNA and RNA are both ribonucleic acid that are involved in genetic propagation & regulation, the following is a base that is exclusively present in RNA and not DNA.
Answers
The correct answer is uracil.
Uracil (U) refers to one of the four nucleobases in the nucleic acid of RNA, which are signified by the letters, A, G, C and U. The others are cytosine (C), adenine (A), and guanine (G).
In RNA, uracil combines with adenine through two hydrogen bonds. In DNA, the nucleobase uracil is substituted by thymine. Uracil is energetically less expensive to generate in comparison to thymine that may hold for its application in RNA.
The answer is Uracil.
Uracil is one of the five main nucleobases found in the nucleic acids of DNA and RNA. The others are adenine, cytosine, guanine, and thymine. However, while the other four are found in DNA, Uracil is usually only found in RNA. Uracil (U), thymine (T), and cytosine (C) are pyrimidine derivatives, and guanine (G) and adenine (A) are basically purine derivatives.
