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.
"Young men undergoing treatment for cancer often want to know how the disease and its treatment affect their chances of fathering healthy children. Our large-scale study shows that there is a slightly higher risk of deformities, but the actual risk of having a child with deformities is nevertheless extremely low. I think this is good news!"
A new study shows that atrial fibrillation--the most common form of sustained heart arrhythmia--can be caused in an unexpected way.
The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.
The rhythm of life may beat far deeper than anyone previously thought. And it may gyrate and pulse in a way that rivals the sensuous choreography of "Dirty Dancing."
A Newcastle University study involving thousands of families is helping prospective parents work out whether they are likely to have sons or daughters.
Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.
The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies. But when the genetic experiment goes awry, the result can be a deadly cancer.
Type 1 (juvenile) diabetes and celiac disease appear to share a common genetic origin, scientists at the University of Cambridge and Barts and The London School of Medicine and Dentistry, have confirmed.
Researchers at the UCSF Ernest Gallo Clinic and Research Center have identified a region on the human genome that appears to determine how strongly drinkers feel the effects of alcohol and thus how prone they are to alcohol abuse.
The Stowers Institute's Baumann Lab has discovered an important step in the maturation pathway of telomerase, the enzyme that replenishes the sequences that are lost at chromosome ends with every cell division.
Since the machinery involved in nucleolar dominance is some of the same machinery that can go haywire in diseases such as cancer, Pikaard and his collaborators' research may have important implications for applied medical research.
A study led by researchers at The University of Nottingham has identified a gene that protects the body from lung cancer.
Scientists at The Institute of Cancer Research have made significant progress in pinpointing two new risk factors associated with the most common childhood kidney cancer, known as Wilms tumour.
If chromosomes snuggle up too closely at the wrong times, the results can be genetic disaster.
The Stowers Institute's Rong Li Lab has published findings that shed light on the ability of cells to adapt to disruptions to their basic division machineries - findings that may help explain how cancer cells elude the body's natural defense mechanisms or chemotherapy treatment.
Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes.
A Swedish research group, partly financed by NWO, has discovered a new mechanism for cell division in a microorganism found in extremely hot and acidic conditions.
Writing in this week's Journal of the American Medical Association , UC Davis M.I.N.D. Institute researchers urge physicians to test for mutations of the fragile X gene in patients of all ages.
Patients with type 2 diabetes who have poor glycemic control and a certain genetic variation have an increased risk of coronary artery disease, according to a study in the November 26 issue of JAMA, the Journal of the American Medical Association.
A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins.
