Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 7, one copy inherited from each parent, form one of the pairs. Chromosome 7 spans about 159 million DNA building blocks (base pairs) and represents more than 5 percent of the total DNA in cells.
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 7 likely contains about 1,150 genes.
Genes on chromosome 7 are among the estimated 20,000 to 25,000 total genes in the human genome.
University of Leicester research which substantially increases our understanding of what causes cell division to go wrong and lead to cancer will be highlighted in a public lecture at the University on Wednesday 14th October at 5.30-6.30pm.
Three young investigators who have taken significant steps toward advancing the understanding of cancer will be the recipients of this year's Paul Marks Prize for Cancer Research, a prize awarded biennially since 2001 to scientists under the age of forty-six by Memorial Sloan-Kettering Cancer Center.

An international team, led by researchers from the University of California, San Diego School of Medicine and the National Eye Institute, has discovered gene variants for glaucoma in a black population. The finding could lead to future treatments or a cure for this disease, which leads to blindness in two million Americans each year.
Cytokines are small proteins secreted by cells that serve as molecular messengers between cells. Pro-inflammatory cytokines - which function in the immune system - may be involved in alcohol dependence (AD). A study of three polymorphisms of the interleukin-1 gene complex (IL-1) and one of the tumor necrosis factor-alpha (TNFα) has found that IL-1 may directly contribute to AD among Spanish Caucasian males.
Penn State College of Medicine researchers, in collaboration with colleagues at the University of Southern California, have taken an important step in understanding the role of stem cells in development of liver cancer.
The National Institutes of Health announced today that it will fund 22 grants on genome-wide studies of how epigenetic changes -- chemical modifications to genes that result from diet, aging, stress, or environmental exposures -- define and contribute to specific human diseases and biological processes.
Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result.
Researchers at The Medical College of Wisconsin in Milwaukee have identified the genetic region in rats responsible for cardiovascular collapse during anesthesia. While it is well known that people have different cardiovascular sensitivity to anesthesia causing some to collapse even when low doses are administered, the mechanism responsible for this susceptibility is not clear.
In the week that the University of Leicester celebrates the 25th anniversary of the discovery of DNA fingerprinting (Thursday September 10) new findings from the world-renowned University of Leicester Department of Genetics reveal for the first time that the male and female do truly communicate -at least at the fundamental genetic level.
An international team of scientists has identified two more genetic risk factors for Alzheimer's disease. The findings are reported in the online edition of the journal Nature Genetics.
The unique mechanism behind the evolutionary survival of the human Y chromosome may also be responsible for a range of sex disorders, from failed sperm production to sex reversal to Turner Syndrome.
A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.
A team of researchers from The Wistar Institute have shown that a large non-coding RNA in mammals and yeast plays a central role in helping maintain telomeres, the tips of chromosomes that contain important genetic information and help regulate cell division. Since this RNA also facilitates the formation of DNA at telomeres-a process that can protect aging cells and destabilize tumor cells-manipulating its expression may be useful in treating cancer and other diseases.
ChromoCure, Inc. (PINKSHEETS: KKUR) released today its development plan for its next generation of chromosomal scanners. The new system has been given the name "CS300" as the next iteration of its current CS200 Chromosomal Scanner design.
In the new print issue of Nature Genetics, scientists in Singapore and Germany report that mutations in the PYCR1 gene cause the rare genetic condition that results in premature skin aging and that is known as "wrinkly skin syndrome."
Genetic variants in a region on chromosome 9q may influence asthma development in Mexican children, according to research published in the August 28 issue of the open-access journal PLoS Genetics.
A new candidate gene for Specific Language Impairment (SLI) has been identified by a research team directed by Mabel Rice from the University of Kansas, in collaboration with Shelley Smith, University of Nebraska Medical Center, and Javier Gayán of Neocodex, Seville, Spain.
A specific genetic region that has been increasingly identified as the strongest genetic link to psoriasis has an even more significant role in the chronic skin disease than has been suspected, University of Utah medical researchers show in a new study.
A specific gene is particularly frequently involved in the development of short stature. Researchers in Heidelberg have now discovered that sequences of genetic material on the X and Y chromosome that regulate this gene are also crucial for growth in children.
