Chromosomes

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

Sex Chromosomes

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

Somatic Cell Hybrid

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

Genetic Linkage Map

Science / Genetics / Genetic Linkage Map: A chromosome map showing the relative positions of the known genes on the chromosomes of a given species. MORE

Autosomal Dominant

Science / Genetics / Autosomal Dominant: A gene on one of the non-sex chromosomes that is always expressed, even if only one copy is present. The chance of passing the gene to offspring is 50% for each pregnancy. MORE

Chromosome Banding

Science / Genetics / Chromosome Banding: A technique for staining chromosomes so that bands appear in a unique pattern particular to the chromosome. MORE

Cloning Vector

Science / Genetics / Cloning Vector: Dna molecule originating from a virus, a plasmid, or the cell of a higher organism into which another dna fragment of appropriate size can be integrated without loss of the vectors capacity for self- MORE
