Answer:
The correct option is the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in the cytoplasm of both prokaryotes and eukaryotes.
Explanation:
The above statement is not true because post-transcriptional modifications do not occur in the cytoplasm of the eukaryotes. Instead, the post-transcriptional modifications occur in the nucleus of the eukaryotes, before the mRNA is transported to the cytoplasm for translation.
On the other hand, the transcription and translation processes for prokaryotes occur in the cytoplasm. Hence, these post-transcriptional modifications do not occur in the prokaryotes.
