cytosine

thymine

Detailed explanation-1: -The nitrogenous base you cant use during replication is Uracil. There are five types of nitrogenous bases in the DNA/RNA structure. For DNA, we have adenine, cytosine, guanine and thymine. For RNA, we have Uracil in place of thymine and the other three.
Detailed explanation-2: -Answer and Explanation: Uracil (U) is the nitrogenous base that is not found on nucleotides used to build the new molecule in transcription.
Detailed explanation-3: -Thymine is the only residue replaced to uracil in the base upon transcription.
Detailed explanation-4: -The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
Detailed explanation-5: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
