Biology question?

before leaving the nucleus, the RNA molecule


a) acquires a pony tail


b) is released from the START signal on the template


c) becomes handicapted


d) stripped of it's introns

Biology question?
the answer is D





A. A Poly-A tail is added, not a pony tail


B. There is nothing attaching it to the START signal, if anything it would be detached from the STOP signal.


C. It becomes capped, not handicapped


D. Correct Answer, only exons leave the nucleus.
Reply:D only exons are left
Reply:Yours Answer is A


Because before leaving the nucleus though nuclear pores. First, a “cap” and a “tail” sequence are added to the ends of the mRNA.





and if u dont beleve me the n just type "before leaving the nucleus, the RNA molecule" in the Google Serach u will find. Okk??
Reply:your answer is "e"














d
Reply:The answer is "D"


because





Answer "A" is plain fake


Answer "B" is wrong- there is a signal that monitors the making of RNA, but START doesn't signal the protein to leave the nucleus.


Answer "C": The molecule is not handicapped in any way.





Answer D is the correct answer because introns stay in the nucleus. Exons do not. They leave the nucleus (think exit- exon) Introns are not needed anyway once the RNA leaves the nucleus.
