In the case of group 1 RNA, which one of the following can’t attack?

1.	In the case of group 1 RNA, which one of the following can’t attack?(a) GMP(b) GDP(c) GTP(d) ATPThe question was asked in a national level competition.This key question is from Post-Transcriptional Modification topic in division Gene Expression : Transcription Prokaryotes of Cytogenetics
Answer» Right CHOICE is (d) ATP To elaborate: It is seen that in the case of group II AUTO splicing RNA the attack is made by the 3’-OH end of the RIBOSE attached to the G base. It is immaterial WHETHER its GMP, GDP or GTP. HOWEVER, A base is not seen to attack in that case.
