Chromosome 6 News and Research

RSS

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.

Move over, Y chromosome - it's time X got some attention

In the first evolutionary study of the chromosome associated with being female, University of California, Berkeley, biologist Doris Bachtrog and her colleagues show that the history of the X chromosome is every bit as interesting as the much-studied, male-determining Y chromosome, and offers important clues to the origins and benefits of sexual reproduction.
