Some specialized cells such as neurons and red blood cells lose their ability to replicate when they mature. Which phase of the cell cycle do you think is terminal for these cells and why?

Some specialized cells such as red blood cells, neurons lose their ability to replicate in the G1 phase of cell cycle. G1 phase is indeed the terminal phase of the cell division as now cell do not divide any more. These cells do not have the necessary nucleus for further cellular replication in the G1 phase. They become mature need not divide anymore.

Cells are the functional unit of life. The cells undergo division to replicate the genetic material and produce daughter cells. The G1 phase of the cell cycle is the phase in which cell lose its ability to mature.

G1 phase of the cell is an intermediate phase, such that the cell occupies the time between cell division in M phase and beginning of replication during S phase. Red blood cells lack the nuclei when they mature because these cells carry oxygen and requires more space to do so. Hence, the cell loses its nucleus. Similarly, neurons lose their ability to mature in the G1 phase.

G1 phase is the terminal phase, in which these cells lose nuclei and their ability to replicate and divide after maturation. These cells do not have the necessary nucleus for further cellular replication in the G1 phase.

Therefore, in the G1 phase the neurons and red blood cells lose nuclei and ability to replicate.
