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.
Chromatin Inc. has announced that it has entered into a research and commercial license agreement with Syngenta Biotechnology Inc. for Chromatin's proprietary gene stacking technology.
In animals with separate sexes, embryos commit to becoming male or female at an early stage.
A new method of constructing artificial plant chromosomes from small rings of naturally occurring plant DNA can be used to transport multiple genes at once into embryonic plants where they are expressed, duplicated as plant cells divide, and passed on to the next generation -- a long-term goal for those interested in improving agricultural productivity.
PTC124, an oral medication that changes the way muscle cells interpret genetic information, holds promise as a treatment for some patients with Duchenne muscular dystrophy (DMD), the Muscular Dystrophy Association ( http://www.mda.org/ ) announced today.
For many Americans, the potential to track one's DNA to a specific country, region or tribe with a take-home kit is highly alluring.
Researchers at the University of Rochester believe they have just confirmed a controversial theory of evolution.
Help with assigning gender could one day be at hand for intersex individuals whose genital phenotypes and sex chromosomes don't match, thanks to the discovery of a stable sex hormone signature in our cells.
In the November 1st issue of G&D, Dr. Michael Cleary (Stanford University School of Medicine) and colleagues identify the gene Meis1 as a critical player in the establishment of leukemia stem cells, and the development of MLL leukemia.
The first research to show the involvement of a gene known as Dmp1 in human lung cancer will hopefully lead to an increased understanding on what goes wrong at the cellular level to cause the disease, according to researchers from Wake Forest University School of Medicine reporting in Cancer Cell .
Although defects in the "breast cancer gene," BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery.
Like a crossword-puzzle solver who uses the letters in some answers to figure out others, researchers at Dana-Farber Cancer Institute and an international group of collaborators have used data on genes involved in inherited forms of breast cancer to identify a gene linked to non-hereditary cases of the disease.
Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first?
Keck Graduate Institute (KGI) announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes."
Scientists may have discovered a new way of killing tumours in what they hope could one day lead to alternative forms of cancer treatments.
Researchers at Cold Spring Harbor Laboratory (CSHL) have discovered three genes that interact with cancerous results in 20% of lung cancers.
University of California, Irvine scientists have discovered how to reverse the learning and memory problems inherent in the most common form of mental impairment.
Researchers in the United States and Sweden have identified a genetic region associated with increased risk of rheumatoid arthritis (RA), a chronic and debilitating inflammatory disease of the joints that affects an estimated 2.1 million Americans.
A test to detect the very early stages of cancer could one day result from new research by Cardiff University scientists.
Some benefits of motherhood are intangible, but one has been validated through biostatistical research: women who bear children have a reduced risk of developing breast cancer.
