A marker chromosome mar is a structurally abnormal chromosome in which no part can be identified. The significance of a marker is very variable as it depends on what material is contained within the marker. It is essentially a partial trisomy . However sometimes the marker is composed of inactive genetic material and has little or no effect. There are some markers that are passed down through a family with little effect. There are some markers that arise as new events. Often, markers are not passed down as they can be lost during cell division due to their small size. There are some individuals who have multiple markers. When special studies are performed to identify the material more conclusions can be drawn about the effects of the marker. There is a more common marker called inverted duplication of chromosome 15. This is a specific syndrome that has developmental delays and physical variations and often seizures as its features. A difficult situation arises when a marker chromosome is found on a prenatal study such as amniocentesis. If the marker is not one of the more common markers and neither parent has the marker, it can be very difficult to predict the effects of the marker. Usually, if a parent carries the same marker, the effect is much less.

Unreferenced date December 2009 Chromosome jumping is a tool of molecular biology that is used in the physical genome project mapping of genome s. It is related to several other tools used for the same purpose, including chromosome walking . Chromosome jumping is used to bypass regions difficult to cloning clone , such as those containing repetitive DNA , that cannot be easily mapped by chromosome walking, and is useful in moving along a chromosome rapidly in search of a particular gene . In chromosome jumping, the DNA of interest is identified, cut into fragments with restriction enzyme s, and circularised the beginning and end of each fragment are joined together to form a circular loop . From a known DNA sequence sequence a primer molecular biology primer is designed to DNA sequencing sequence across the circularised junction. This primer is used to jump 100 base pair kb 300 kb intervals a sequence 100 kb away would have come near the known sequence on circularisation. Thus, sequences not reachable by chromosome walking can be sequenced. Chromosome walking can be used from the new jump position in either direction to look for gene like sequences, or additional jumps can be used to progress further along the chromosome.

Several chromosome regions have been defined by convenience in order to talk about gene locations. Most important is the distinction between chromosome region p and chromosome region q . These are Virtuality virtual regions that exist in all chromosome s. During cell division , the molecules that compose chromosomes DNA and protein s suffer a condensation process called the chromatin condensation , and forms a compact and small complex called a chromatid. In diploid organisms, sister chromatids are attached to each other by the centromere . The centromere divides each chromosome into two regions the smaller one, which is the p region, and the bigger one, the q region. Usually, as a convention, the p region is represented in the upper part of an image while the q region is in the bottom part. At either end of a chromosome is a telomere , a cap of DNA that protects the rest of the chromosome from damage. The areas of the p and q regions close to the telomeres are the subtelomere s, or subtelomeric regions. The areas closer to the centromere are the pericentronomic regions. Finally, the interstitial regions are the parts of the p and q regions that are close to neither the centromere nor the telomeres, but are roughly in the middle of p or q .

Dicentric chromosomes form when two chromosome segments from different chromosomes or from the two chromatids of a single one , each with a centromere, fuse end to end, with loss of their acentric fragments. Dicentrics, despite their two centromeres, may be mitotically stable if one of the two centromeres is inactivated, or if the two centromeres always coordinate their movement to one or the other pole during anaphase. Such chromosomes are formally called pseudodicentric. The most common pseudodicentrics involve the sex chromosomes or the acrocentric chromosomes Robertsonian translocation .

Orphan date April 2012 The genetics genetic technique of chromosome landing is a method of molecular cloning cloning of a gene of interest from a clone library . It is based on the principle that the expected average between genetic marker marker genetic distance distance s can be smaller than the average insert length of a clone library containing the gene of interest. From the abstract of PMID 7716809 The strategy of chromosome walking is based on the assumption that it is difficult and time consuming to find DNA markers that are physically close to a gene of interest. Recent technological developments invalidate this assumption for many species. As a result, the mapping paradigm has now changed such that one first isolates one or more DNA marker s at a physical distance from the targeted gene that is less than the average insert size of the genomic library being used for clone isolation. The DNA marker is then used to Genetic screen screen the library and isolate or land on the clone containing the gene, without any need for chromosome walking and its associated problems. Chromosome landing, together with the technology that has made it possible, is likely to become the main strategy by which map based cloning is applied to isolate both major genes and genes underlying quantitative traits in plant species.
