Multicellular organisms use cell division, mitosis, for growth and the maintenance and repair of cells and tissues. There are few cells in the body that do not undergo mitosis: most somatic cells divide regularly, some more than others. Single-celled organisms may use cell division as their method of reproduction. Regardless of the reason for mitosis, the process ensures genetic continuity. Consider the model of the cell cycle. Which detail (s) from the model best support the argument that cell division promotes genetic continuity?

Samson Huber · Answer 1

The phases are

Inter phase. Growth phase. Replication or Synthesis phase. Second Growth phase. Mitosis

Nayeli Clay · Answer 2

Genetic continuity is maintained by the Replication or Synthesis phase and the Mitosis phase of the Cell cycle.

Explanation:

The Cell Cycle can be divided into the following phases, G0 - Interphase. G1 - Growth phase. S - Replication or Synthesis phase. G2 - Second Growth phase. M - Mitosis. Of all the above phases, in the S phase the replication or doubling of the genetic material, that is, the DNA, occurs for equally distributing the genetic material to both the daughter cells. The M or the Mitosis phase is also essential to ensure that the distribution of the genetic material occurs accurately among the daughter cells. Hence, a genetic continuity is maintained across the generations of the cells.
