Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does the mRNA go when it leaves the nucleus?
A
Mitochondria
B
Cytoplasm
C
Golgi apparatus
D
Cell membrane
Explanation: 

Detailed explanation-1: -After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins. Translation happens on the ribosomes floating in the cytosol, or on the ribosomes attached to the rough endoplasmic reticulum.

Detailed explanation-2: -Export of mRNA from the nucleus to the cytoplasm takes place through a pore complex in the membrane of the nucleus. Export is believed to involve the attachment of an adapter protein to the mRNA.

Detailed explanation-3: -Molecular guides As you mention, after the mRNA is made in the nucleus, it exits out into the cytoplasm via the nuclear pore.
