Messenger RNA editing is an example of gene expression at the _________ level.
A)transcriptional
B)translational
C)posttranslational
D)posttranscriptional
E)preternatural

Question

Quizplus · Accepted Answer

Messenger RNA editing occurs after transcription and involves changes in the nucleotide sequence of mRNA. Therefore, it is an example of gene expression at the posttranscriptional level. Transcriptional regulation involves controlling the initiation and frequency of transcription, translational regulation involves controlling the rate of protein synthesis, and posttranslational regulation involves modifying and processing the protein product after translation. "Preternatural" seems to be a typo or incorrect option, so it is not a valid choice.
