Because mRNA is a single stranded molecule where as DNA forms a double helix. Therefore mRNA is a smaller molecule than DNA so can leave the nucleus
ALSO
mRNA has been processed post-translation. This means a 5' cap has been added and a 3' poly(A) tail has been added. This 5' cap, which DNA does not have, allows mRNA to leave the nucleus through nuclear pores.
All above is good idea all ,
And me have something that need to include more. First time DNA can't leave from nucleus ,so DNA change to be nucleotide then mRNA go into nucleus and duplication ,A , T, C, G of DNA to be U,A,G,C. During mRNA get out from nucleus , mRNA will go to ribosomes to produce protein to take care cell.

What does mRNA stand for and why does it have to be made?
Messanger RNA and it sends the messages for the DNA because the DNA cannot leave the nucleus
What molecule cannot leave the nucleus?
Dna. Yet, surprisingly, any other molecule that I can think of may exit and enter.
Function of nucleus pore?
It allows RNA, that is transcribed from a DNA in the nucleus, to leave the the nucleus.
Why do you have a messenger RNA?
mRNA carries the code that was transcribed from DNA out to the ribosome to form the correct amino acid chain. So, yes, in a way mRNA is a messenger to the ribosomes since DNA cannot leave the nucleus.
Why must you go through the process of changing DNA into rna?
In order to protect the DNA from potentially damaging reactions in the cytoplasm, the nucleus prevents the DNA from leaving it. Therefore it must be transcribed by mRNA, which can leave the nucleus.

Which one can leave the nucleus: DNA or RNA?
RNA can leave the Nucleus.

Function of nucleus pore?
It allows RNA, that is transcribed from a DNA in the nucleus, to leave the the nucleus.
What is the term for DNA after it has left the nucleus?
The DNA found in the nucleus does not leave the nucleus. Instead, a copy of this DNA is carried on mRNA out of the nucleus and to the ribosomes. By keeping the DNA in the nucleus, it is protected from degradation - so a "master copy" of the instructions can be kept safe.
How does mRNA leave the the nucleus after copying DNA?
nucleic acids
What molecule is able to leave the nucleus with the genetic code?
Perhaps you are talking about messenger RNA, mRNA, that is transcribed from DNA in the nucleus and leaves the nucleus to go into the cytosol where it docks with a ribosomal subunit where translation takes place.
Why do you have a messenger RNA?
mRNA carries the code that was transcribed from DNA out to the ribosome to form the correct amino acid chain. So, yes, in a way mRNA is a messenger to the ribosomes since DNA cannot leave the nucleus.
Where does DNA change to RNA in the cell?
Because DNA never leaves the nucleus, it is in there that DNA is transcribed onto a mRNA molecule which then leave the nucleus through the nuclear pores to head out to a ribosome to be translated.
Is DNA a nucleus?
The nucleus contains DNA. The DNA is found in the nucleus.
What is confined to the nucleus of the eukaryocyte?
In the nucleus is DNA which is contained on chromosomes. These never leave the nucleus. Instead, when the DNA needs to be used to create new cells, something called rNA copies the DNA code to take it to various other sites. Inside of the nucleus there is also nucleic acid.
Why must you go through the process of changing DNA into rna?
In order to protect the DNA from potentially damaging reactions in the cytoplasm, the nucleus prevents the DNA from leaving it. Therefore it must be transcribed by mRNA, which can leave the nucleus.
