Scientists classify living things in order to organize and make sense of the incredible diversity of life. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA.

What happens is that the RNA<span> is synthesized from the template and RNA polymerase moves along the DNA, elongating the RNA transcript molecule; an enzyme forms the hydrogen bonds between the bases of the DNA strand and the complementary bases of the RNA molecule found in the nucleus.</span>

Answer:
removal of introns, addition of 5' cap and 3' tail to mRNA.
Explanation:
The mRNA is processed before it leaves nucleus. The introns are removed and exons are remain in mRNA. This process is called splicing. The 5' end is attached with a cap and 3' is attached with a polyadenylated tail. Thus mRNA is processed with these process before it leaves the nucleus.
