Chromosome 8 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 8, one copy inherited from each parent, form one of the pairs. Chromosome 8 spans about 146 million DNA building blocks (base pairs) and represents between 4.5 percent and 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 8 likely contains between 700 and 1,100 genes.

Genes on chromosome 8 are among the estimated 20,000 to 25,000 total genes in the human genome.

Qatar genomics study reveals key historical and social insights into Arab populations

Researchers in Qatar have unveiled a high-resolution map of the genetic structure of Arab and Middle Eastern populations, providing new insights into human history in the region and ancestral patterns that may help to explain local human traits and disease risks.

Artificial intelligence tool to predict the risk of psychotic illness

One-third of children with a microdeletion of chromosome 22 will later develop a psychotic illness such as schizophrenia. But how do we know which of these children might be affected? Today, various studies have contributed to the understanding of the neurobiological mechanisms that are associated with the development of psychotic illnesses.

Growing wheat varieties with biological nitrification inhibition trait could increase yields

An international collaboration has discovered and transferred to elite wheat varieties a wild-grass chromosome segment that causes roots to secrete natural inhibitors of nitrification, offering a way to dial back on heavy fertilizer use for wheat and to reduce the crop's nitrogen leakage into waterways and air, while maintaining or raising its productivity and grain quality, says a new report in the Proceedings of the National Academy of Sciences of the United States of America.

Uppsala researchers find solution to long-standing biological search enigma

How the cell can mend broken DNA using another DNA copy as template has puzzled researchers for years. How is it possible to find the correct sequences in the busy interior of the cell? Researchers from Uppsala university have now discovered the solution; it is easier to find a rope than a ball if you are blindfolded.
