Is Thymine Present in Rna?

Adenine and guanine are found in RNA and DNA in terrestrial life, whereas thymine is only found in DNA and uracil only in RNA.

Is thymine in DNA or RNA?

Thymine (/ˈθaɪmɪn/) (symbol T or Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil.

Is thymine present in tRNA?

Note that thymine (=5-methyl uracil), which is normally only found in DNA, is also found in the TψC-loop of tRNA, where it is attached to ribose and is made by methylation of uracil after transcription. In addition to uracil, guanine, adenine, and cytosine may also be modified by methylation.
