One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

Chromosome 2 is the second largest of the 46 chromosomes found in human cells. Chromosome 2 spans 243 million base pairs and makes up around 8% of the total DNA present within our cells. The base ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

Sex chromosomes are unusually labile systems, with frequent shifts between male and female heterogamety and with a large variety in the precise number and types of chromosomes. The lability is further ...

Chromosome 5 is the fifth largest chromosome of the 23 chromosomal pairs in humans and represents nearly 6% of the total DNA. Despite being one of the largest chromosomes, chromosome 5 has a low gene ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share upwards ...

In the early 1980s I met and began an unofficial training with Anna Freud—Sigmund Freud's youngest daughter, and his only child to follow him into psychoanalysis. I was a young social scientist who ...

A research paper highlights how spiny rats have developed a new male-determining gene. A recent study suggests a surprising future for human reproduction: the Y chromosome, which is crucial for ...

Researchers have created male mice with no trace of a Y chromosome, supposedly the defining hallmark of being male. Reproductive biologist Monika Ward of the University of Hawaii in Honolulu and ...

The centromere is necessary for the transport of chromosomes during cell division and, therefore, for the correct ...

The good news is two branches of rodents have already lost their Y chromosome and have lived to tell the tale. A new paper in Proceedings of the National Academy of Science shows how the spiny rat has ...
