Prokaryote

Science / Genetics / Prokaryote: Cell or organism lacking a membrane-bound, structurally discrete nucleus and other subcellular compartments. Bacteria are examples of prokaryotes.

Chromosome

Science / Genetics / Chromosome: The self-replicating genetic structure of cells containing the cellular dna that bears in its nucleotide sequence the linear array of genes. In prokaryotes, chromosomal dna is circular, and the entire MORE

Eukaryote

Science / Biology / Eukaryote: A type of cell found in many organisms including single-celled protists and multicellular fungi, plants, and animals; characterized by a membrane-bounded nucleus and other membraneous organelles; an o MORE

Linkage

Science / Biology / Linkage: The condition in which the inheritance of a specific chromosome is coupled with that of a given gene. The genes stay together during meiosis and end up in the same gamete. MORE

Chromosomes

Science / Biology / Chromosomes: Structures in the nucleus of a eukaryotic cell that consist of DNA molecules that contain the genes. MORE

Eukarytote

Health / Disease / Eukarytote: An organism whose cells contain a true nucleus, such as a plants, animals, fungi and protozoa (cf prokaryote) MORE
