Which of the following better describes a typical, actively translated mRNA in its journey from the nucleus to the cytosol?

A) Initially in a circular conformation, the mRNA linearizes, enters the cytosol (5' end first), and remains linear.
B) Initially in a circular conformation, the mRNA linearizes, enters the cytosol (3' end first), and remains linear.
C) Initially linear, the mRNA enters the cytosol (5' end first), and adopts a circular conformation.
D) Initially linear, the mRNA enters the cytosol (3' end first), and adopts a circular conformation.
E) Initially linear, the mRNA enters the cytosol (3' end first), and remains linear.
