The following statements are made with reference to the fact that tRNAs are known to possess thymine (T) in their sequence: A. RNA polymerase III utilizes TTP as one of the substrates. B. Like any other RNA polymerase, RNA polymerase III utilizes rUTP, but when it reaches a looped structure, it binds to S-adenosylmethionine to methylate the C-5 position of the incorporated U, resulting in a thymine in a co-transcriptional manner. C. During transcription of tRNA genes at designated positions, DNA polymerase replaces RNA polymerase III to incorporate T in the tRNA transcript. D. A specific methyltransferase utilizes a methyl group donor to post-transcriptionally modify specific U residues into T residues. E. Uracil to thymine conversion occurs in a large number of tRNAs in the TΨC loop. Which option contains all the correct statements?
