In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear ...

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

The basic enzymology of DNA replication is well conserved among all life, and it has recently been shown that eukaryotic chromosomes are also highly catenated along their lengths. We expect that our ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically ...

Located at the ends of eukaryotic chromosomes and synthesized by the enzyme telomerase, telomeres maintain the length of chromosomes. The majority of human cancer cells express high levels of ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Accordingly, defects in chromosome replication are a major driver of the genomic instability observed in cancer cells. To understand the molecular mechanisms by which eukaryotic cells carry out and ...

"In fungi and many other so-called eukaryotic organisms, however, horizontal gene transfer in the form of entire chromosomes ...
