Astudent researcher inserts an mrna molecule into a eukaryotic cell aftershe has removed its 5′ cap and poly-a tail. which of the following processes would you expect her to find to have occurred? a)the mrna is quickly converted into a ribosomal subunit. b)the cell adds a new poly-a tail to the mrna. c)the mrna attaches to a ribosome and is translated, but more slowly. d)the molecule is less stable because it is not protected at the 5′or 3’ ends

The molecule is less stable because it is not protected at the 5′or 3’ ends

Explanation:

The RNA transcription occurs in the eukaryotic cell in a complex way. It has to under-went certain processes to become a mRNA or messenger RNA. To convert into an actual messenger RNA addition of 5’cap and poly A tail with the RNA is done.

Both of them are helpful in protecting the transcription and translating it on the ribosome. So, a removal of them would make the process unprotected and unstable as the cap prevents the transcription from breaking down and the tail makes it stable.
