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.
