Note that because the two polynucleotides that make up double-stranded DNA ... this highly compacted DNA is then arranged into structures called chromosomes. Chromosomes take different shapes ...

Each cell with a nucleus contains chromosomes, which are made from DNA Human body cells each contain 23 pairs of chromosomes, half of which are from each parent. So, human gametes (eggs and sperm ...

How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...

Chromosomes are thin strands of DNA (deoxyribonucleic acid). A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are different ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

For this, the cell must duplicate its DNA – its genome – and segregate it equally into two new daughter cells. To prepare the 46 chromosomes of a human cell for transport to the daughter cells ...

A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into overlapping loops that repel each other, which then stack to create a rod-like ...

Utrecht University has appointed Bas van Steensel as Special Professor of Chromosome Biology. Van Steensel will lead fundamental research into how chromosomes function and how genetic information is ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

Males, with their single X chromosome, arise due to errors during X chromosome segregation and make up just 0.1 to 0.2 percent of the population ... To zoom in on changes in chromosome organization ...
