Similarly, if we look at a person’s karyotype, we might notice that a band is missing from the short arm of chromosome 1. This tells us that there is a deletion on chromosome 1. The Molecular Approach. Let’s return to the phone book example. If we just look at the closed phone book, we do not know which section is missing. M.A. Ferguson-Smith, in Encyclopedia of Genetics, Somatic cells contain a specific number of pairs of chromosomes, the particular number depending on the species. When one member of a pair of chromosomes is missing in the individual's karyotype (see Karyotype), this is given the term monosomy for the missing chromosome. Monosomy for an autosome leads to severe developmental abnormality. Chromosome definition is - any of the rod-shaped or threadlike DNA-containing structures of cellular organisms that are located in the nucleus of eukaryotes, are usually ring-shaped in prokaryotes (such as bacteria), and contain all or most of the genes of the organism; also: the genetic material of a virus. Aug 08, · Chromosome browsers are available at 23andMe, Family Tree DNA, MyHeritage DNA, and are promised to be coming soon for LivingDNA customers.

Not only are the Looking at chromosomes book of most eukaryotes much more complex than those of prokaryotes, but the DNA of eukaryotic cells is also organized differently from that of prokaryotic cells.
The genomes of prokaryotes are contained in single chromosomes, which are usually circular DNA molecules. In contrast, the genomes of eukaryotes are composed of multiple chromosomes, each containing a Cited by: 1.

We call this the cytogenetic approach to diagnosing chromosome abnormalities. This approach involves examining a person’s chromosomes under a microscope. A cytogeneticist looks at the chromosomes to see whether there are any missing or extra pieces. This means that the only time chromosomes look like an “X” is after DNA replication has taken place and the chromosomes have condensed.
