Instead of Thymine as a nitrogen base, RNA has
|
|
Adenine
|
|
|
sugar
|
|
|
uracil
|
|
|
phosphate
|
Explanation:
Detailed explanation-1: -Uracil is present only in RNA, whereas thymine is present only in DNA. Thus, thymine is the nitrogenous base which is not present in RNA.
Detailed explanation-2: -Nucleic Acids: DNA and RNA Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, the thymine is replaced by uracil (U). The chemical structures of A, G, C, T, and U are shown in (Fig. 1.5A).
Detailed explanation-3: -mRNA uses uracil instead of thymine because mRNA is RNA and RNA has uracil instead of thymine.
Detailed explanation-4: -Thymine. Cytosine is common for both DNA and RNA, and thymine is present in DNA. Uracil is present in RNA at the place of thymine.
