1. Genetic Clone Stability & Replication

Key Concepts & Definitions

  • Clone: A group of cells derived from a single ancestral cell through mitosis, genetically identical barring mutations.
  • Mitotic Replication: The process by which DNA is duplicated before cell division, ensuring each daughter cell receives an identical genome.
  • Genetic Stability: The preservation of the genome's structure and content across cell generations, primarily maintained through accurate DNA replication and segregation.
  • Mutations: Changes in the DNA sequence that can occur during replication, leading to genetic variation within clones.
  • Sub-clone: A subgroup within a clone that has acquired specific mutations, making it genetically distinct from the original clone.
  • Genetic Accident: An event such as mutation or chromosomal aberration occurring during cell division, potentially leading to genetic diversity or instability.
