Study Notes
Chromosome Classification Terms
- Metacentric: Chromosomes with centromere located centrally, resulting in two equal arms.
- Telocentric: Chromosomes have a centromere positioned at one end, producing a single long arm.
- Acrocentric: Chromosomes where the centromere is located very close to one end, leading to one short arm and one long arm.
Morphological Classification
- Homomorphic: Refers to chromosomes that are morphologically similar, this term often describes the XX chromosome pair.
- Heteromorphic: Describes chromosomes that are dissimilar in appearance, commonly refers to the XY chromosome pair.
Cell Type Classification
- Diploid: Cells containing two complete sets of homologous chromosomes, typical in somatic cells.
- Haploid: Cells that have one complete set of chromosomes, usually found in gametes (sperm and egg cells).
Chromosomal Structure and Function
- Kinetochore: Protein structure on the chromosome where spindle fibers attach, essential for chromosome movement during cell division.
- Centromere: The constricted region of the chromosome where the kinetochore is located, playing a crucial role in chromosome segregation.
