Explanation:
The processing of mRNA to a fully mature eukaryotic mRNA requires addition of a 5' cap (Capping) and 3' poly(A) tail ( polyadenylation) to the ends of the transcript, and removal of any intervening introns by splicing. Once processing is completed, the mRNP, which consists of mRNA and associated proteins, is ready for export from the nucleus.
During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.
