Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 6, one copy inherited from each parent, form one of the pairs. Chromosome 6 spans about 171 million base pairs (the building blocks of DNA) and represents between 5.5 percent and 6 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 6 likely contains between 1,100 and 1,600 genes.
Genes on chromosome 6 are among the estimated 20,000 to 25,000 total genes in the human genome.
New York University chemists have employed a computer simulation whose results have enhanced scientific understanding of the DNA transcription process. The study, funded by the National Institutes of Health, appears in the June 7 issue of the Proceedings of the National Academy of Sciences.
Scientists at Memorial Sloan-Kettering Cancer Center (MSKCC) have uncovered the structure of a network of proteins that help regulate the life cycle of cells. Understanding the network's physical layout is an important step toward learning its precise function, and in finding ways to correct flaws in the system that could lead to cancer.
A molecular "syringe" sticks out of the bacteria, pokes a hole in a nearby cell, and squirts in venomous proteins that hijack the cell's machinery.
Despite an enormous range of treatments, obscure lotions and tinctures there appears to be very few successful counter-measures for hair loss in men. Beginning with receding hairlines, every second man suffers from hair loss to some degree, and it has always been suspected that hereditary factors are important in causing hair loss.
When genes are deleted on a particular section of chromosome 11, the result is an aggressive form of the childhood cancer neuroblastoma. A new study suggests that detecting this genetic deletion during the initial evaluation of children with neuroblastoma may indicate to physicians that they should recommend a more aggressive regimen of chemotherapy to fight the cancer.
By deciphering the ingenious mechanism used by a particular enzyme to modify bacterial chromosome chemistry, scientists have come a step closer to designing a new kind of drug that could stop virulent bacterial infections in their tracks. Their research will be published in the May 6 issue of the journal Cell.
A powerful laboratory technique used by fruit fly geneticists for more than a decade is now available to scientists studying genes and diseases in mice.
Oregon State University researchers have made significant new advances in determining the structure of all possible DNA sequences – a discovery that in one sense takes up where Watson and Crick left off, after outlining in 1953 the double-helical structure of this biological blueprint for life.
Age-related macular degeneration, the leading cause of blindness in the elderly, occurs when a common inherited gene variation is triggered, possibly by an infection, according to a new study led by researchers at Columbia University Medical Center and the University of Iowa, with an international research team.
A team of researchers from Lund University in Sweden have found that exposure to a class of environmental pollutants can change the ratio of sperm carrying male and female chromosomes.
A simple DNA test that is available commercially to help people establish their ancestry could in fact disclose male infertility claims a new study from the University of Leicester.
Why do some cancer cells divide not into two, as cells are supposed to do in mitosis, but into three-four new cells that look thoroughly abnormal? This question was raised as early as the 1890s by the German tumor researcher David Hansemann, who could observe the strange mitosis even using the microscopes of his day. Now another David, Lund University researcher David Gisselsson, has found an answer.
An investigational drug is producing powerful responses in patients resistant to Gleevec, the targeted therapy that helps most people diagnosed with chronic myeloid leukemia (CML), an international research team headed by investigators at The University of Texas M. D. Anderson Cancer Center is reporting.
Scientists at the University of North Carolina at Chapel Hill have identified an enzyme that helps trigger the development of leukemia, a cancer of blood cells.
Scientists have identified a new gene that appears to be linked to a small but significant percentage of familial cancer cases – as well as seemingly randomly occurring malignancies.
A team of scientists from Colombia, the United States and elsewhere has successfully completed a 15-year-plus search for the genetic problems behind the very rare Roberts syndrome, whose physical manifestations often include cleft lip and palate and shortened limbs that resemble those of babies whose mothers took thalidomide during pregnancy.
A detailed analysis of chromosomes 2 and 4 has detected the largest "gene deserts" known in the human genome and uncovered more evidence that human chromosome 2 arose from the fusion of two ancestral ape chromosomes, researchers supported by the National Human Genome Research Institute (NHGRI).
Harnessing the strength of a natural process that repairs damage to the human genome, a researcher from UT Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes.

Mutations in the HFE gene, which is involved in iron regulation, seem to be directly associated with chronic joint disease (or haemophilic arthropathy) among haemophilic patients, claim a team of Portuguese scientists in the April issue of the journal Blood.
