Entity: CHROMOSOME
Chromosome is a threadlike structure made of DNA and protein found in the nucleus of cells. It carries genetic information and plays a crucial role in inheritance.
CHROMOSOME
Etymology
The term 'chromosome' is derived from the Greek words 'chroma' meaning color and 'soma' meaning body, reflecting their ability to be stained and visualized under a microscope.
Definition
Chromosome is a rod-shaped or threadlike DNA-containing structure in the nucleus of eukaryotic cells, carrying genes in a linear order. It contains the genetic material necessary for the development, functioning, and reproduction of organisms.
Historical Context
Chromosomes were first observed in the late 19th century by German scientist Theodor Boveri and have since been extensively studied to understand their role in genetics and heredity.
Cultural Significance
Chromosomes are fundamental to the field of genetics and have revolutionized our understanding of inheritance, evolution, and genetic disorders. They are crucial in determining an organism's traits and characteristics.
Related Concepts
Other related concepts include genes, DNA, karyotype, and genetic disorders, all of which are interconnected with chromosomes in the study of genetics.
