The following statements are made with reference to the fact that tRNAs are known to possess T in their sequence. A. RNA polymerase Ill utilizes TTP as one of the substrates. B. Like any other RNA polymerase, RNA polymerase III also utilizes UTP but when the RNA pol III reaches a looped structure it binds to S-adenosylmethionine to methylate C-5 position of the incorporated U to result in a thymine in a co-transcriptional manner. C. During transcription of tRNAgenes at thedesignated positions, DNA polymerase replacesRNA polymerase III to incorporate T in the tRNAtranscript D. A specific methyl -transferase utilizes a methyl group donor to post transcriptionally modify the specific U residues into T residues. E. Uracil to thymine conversion occurs in a large number of tRNAs in the TѰC loop. The option with all the correct statements is
