DNA is housed within the nucleus, but the mRNA code needs to leave in order to be translated into a protein. How does the mRNA code leave the nucleus if the nucleus is surrounded by the nuclear envelope?
A) The nuclear envelope dissolves in order to allow the mRNA code to leave.
B) The nuclear envelope contains pores that allow the mRNA to exit through.
C) A vesicle will bud off from the nuclear envelope containing the mRNA.
D) The mRNA will be coded into a protein within the nucleus. Then the protein leaves the nucleus.

The nuclear envelope contains large pores that allow for the selective transport of molecules, including mRNA, into and out of the nucleus. The mRNA can exit the nucleus through these pores and be transported to the ribosomes for translation into a protein. The nuclear envelope itself does not need to dissolve, and the mRNA does not need to be packaged in a vesicle or coded into a protein within the nucleus in order to exit the nucleus.
