dna replication

• +

  • DNA replication in interphase ensures the accurate duplication of genetic information, leading to diploid daughter cells through mitosis. Without this DNA replication, mitosis would create non-functioning haploid daughter cells.
• +

  • The correct DNA amount is advantageous for coding functional proteins, ensuring accurate phenotypic expression and favourable characteristics.
• +

  • This adaptation supports the organism's ability to thrive and reproduce in its environment, ultimately enhancing the continuity of the species.
• -

  • DNA replication may potentially introduce errors in the DNA code, known as mutations.
• -

  • These mutations may result in non-functional proteins, leading to incorrect phenotypic expression and potentially unfavourable characteristics.
• -

  • Such unfavourable traits can reduce the population's ability to survive and reproduce under selective pressure, ultimately leading to the discontinuity of the species.
