D)postmitotically
E)premitotically

Question

Quizplus · Accepted Answer

Modifications to the nucleotides of pre-rRNAs are made posttranscriptionally, meaning after the RNA molecule has been transcribed from DNA. Pretranscriptional modifications refer to changes made to the DNA sequence before transcription, which do not affect the RNA molecule directly. Posttranslational modifications occur after translation of the RNA molecule into protein. Postmitotic and premitotic refer to events occurring after or before cell division, respectively, and are not relevant to RNA processing.
