Question: In an experimental situation, a student researcher inserts an mRNA molecule into a eukaryotic cell after he has removed its 5' cap and poly-A tail. Which of the following would you expect him to find?

A) The molecule is digested by restriction enzymes in the nucleus.

B) The MRNA could not exit the nucleus to be translated.  

c) The molecule is digested by exonucleases since it is no longer protected at the 5' end.

D) The cell recognizes the absence of the tail and polyadenylates the mRNA.

E) The molecule attaches to a ribosome and is translated, but more slowly.

c) The molecule is digested by exonucleases since it is no longer protected at the 5' end.

Explanation:

The primary transcript formed by transcription in eukaryotes is modified by the addition of a structure called 5' cap at its 5' end. It refers to 7-methylguanosine that is linked to the 5' end of the primary transcript. The presence of 7-methylguanosine at the 5' end protects the mature mRNA against digestion by ribonucleases. Therefore, insertion of mRNA without a 5' cap into a eukaryotic cell would result in the breakdown of the inserted mRNA.

the answer is golgi apparatus

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
