Chromosome Summary

Chromosomal Aberrations Chromosomal aberrations are abnormalities in the structure or number of chromosomes and are often responsible for genetic disorders. For more than a century, scientists have be... Read more

Chromosomal Theory of Inheritance The chromosomal theory of inheritance is the idea that genes, the units of heredity, are physical in nature and are found in the chromosomes. The theory arose at the ... Read more

Chromosome, Prokaryotic The bacterial or prokaryotic chromosome differs in many ways from that of the eukaryote. The term "eukaryote" comes from the Greek and means "true nucleus.... Read more

Chromosomes The genetic material in plants, animals, and fungi is called deoxyribonucleic acid (DNA), a long, linear polymer that is physically organized at the microscopic level into chromosomes. Chr... Read more

Chromosome Chromosomes are thread-like bodies in the cell nucleus of all plants and animals that hold the genes--the blueprints of heredity. Each chromosome carries a single strand of DNA that threads... Read more

Chromosome A chromosome consists of the body's genetic material, the deoxyribonucleic acid, or DNA, along with many kinds of protein. Chromosomes contain the genes, or segments of DNA, that encode for... Read more

Chromosome Mapping and Sequencing A chromosome map describes the order of genes and other markers, and the spacing between them on the chromosome. These maps are constructed with different levels of c... Read more

Chromosome Structure and Morphology Chromosomes are microscopic units containing organized genetic information, located in the nuclei of diploid and haploid cells (e.g. human somatic and sex cells), a... Read more

Sister Chromatid Exchange During the S-phase of the cell cycle, DNA is replicated and each chromosome is present in a duplicated state with the two genetically identical chromatids joined together at ... Read more

Chromosomes, Prokaryotic The genetic material of microorganisms, be they prokaryotic or eukaryotic, is arranged in an organized fashion. The arrangement in both cases is referred to as a chromosome. T... Read more
