Pie

Answer:

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,
  1. G0- Interphase.
  2. G1 - Growth phase.
  3. S - Replication or Synthesis phase.
  4. G2 - Second Growth phase.
  5. 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.
