Key Concepts & Definitions

  • Cell Division: The biological process where a parent cell divides to produce two or more daughter cells, essential for growth, repair, and reproduction.
  • Mitosis: A type of cell division resulting in two genetically identical diploid daughter cells, used for growth and tissue repair.
  • Meiosis: A specialized form of cell division that produces four genetically diverse haploid gametes (sperm and eggs), crucial for sexual reproduction.
  • Chromosome: A structure composed of DNA and proteins that carries genetic information; visible as distinct entities during cell division.
  • Sister Chromatids: Identical copies of a chromosome connected at a centromere, formed during DNA replication in the S phase.
  • Homologous Chromosomes: Pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content, involved in meiosis.
