Answer:

means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present

Explanation:

Mature red blood cells (also known as erythrocytes) don't contain nuclei. The red blood cells that enter the bloodstream eject their nuclei in order to have more space for transporting hemoglobin, a protein whose main function is to bind molecular oxygen. Erythrocytes have a life span period of three (3) to four (4) months. During this period, the mRNA of the hemoglobin genes must remain intact in order to synthesize hemoglobin proteins (i.e., their subunits). Moreover, in mature red blood cells, the levels of the enzymes involved in the degradation of cytoplasmic mRNA (ribonucleases) must also be low to avoid bulk mRNA degradation.

Answer:

Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
