Explanation:
Before it leaves the nucleus, the mRNA is spliced to create mature mRNA. This splicing involves that cutting out of introns, leaving only the exons - which are the segments which code for a protein. Before it leaves the nucleus, the mRNA is spliced once again to create mature mRNA.
The correct answer would be D, because the ending result for mitosis is 2 diploid cells, meaning the number chromosomes are the same. While in meiosis, the ending result is 4 haploid cells. Because the cell was divided twice, this means that each daughter cell has half of the number of chromosomes.
