|
|
The mRNA could not exit the nucleus to be translated.
|
|
|
The molecule is digested by restriction enzymes in the nucleus.
|
|
|
The molecule is digested by exonucleases since it is no longer protected at the 5’ end.
|
|
|
The cell recognizes the absence of the tail and polyadenylates the mRNA.

Detailed explanation-1: -Which of the following is most likely to occur if a researcher removes the 5’ cap and poly-A tail of an mRNA and inserts the mRNA molecule into a eukaryotic cell? The molecule will be degraded by enzymes.
Detailed explanation-2: -Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
Detailed explanation-3: -After the transcription of DNA to mRNA is complete, translation-or the reading of these mRNAs to make proteins-begins.
Detailed explanation-4: -In eukaryotic cells, transcription takes place in the nucleus . During transcription, DNA is used as a template to make a molecule of messenger RNA ( mRNA ). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
