Science / Genetics / Chromosomes: The self- replicating genetic structures 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 genome is carried on one chromosome. Eukaryotic genomes consist of a number of chromosomes whose dna is associated with different kinds of proteins.
Science / Biology / Sex Chromosomes: The chromosomes that determine the sex of an organism. In humans, females have two X chromosomes, and males have one X chromosome and one Y chromosome. Chromosome that determines the gender (sex) of t MORE
Science / Genetics / Somatic Cell Hybrid: Hybrid cell line derived from two different species: contains a complete chromosomal complement of one species and a partial chromosomal complement of the other: human/hamster hybrids grow and divide, MORE
