Chromothripsis enables cancer cells to evolve and resist treatment. With their new findings, researchers hope to explore ways ...

In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

Scientists remain divided over whether the human Y chromosome will eventually vanish. But clinicians say the real concern ...

The human Y chromosome, the determinant of male sex, has finally been completely sequenced. What it unveils could prove crucial to understanding the Y chromosome’s puzzling origins, and — pertinently ...

Basic biology has it that girls are girls because they have two X chromosomes — the things inside cells that carry our genes. Boys are boys because they have one X and one Y. Recently, though, there's ...

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 ...

Expert says the Y chromosome will disappear in about 125,000 years. LONDON, April 28, 2008— -- Imagine a world without men: Lauren Bacall but no Bogie, Hillary Clinton but no Bill, no Starsky or ...

A study revealed that the Y chromosome, which determines male sex, is degenerating and may vanish in a few million years. Research on Sry-deficient Amami spiny rats, which lost the Y chromosome but ...

Chromosome 3 is the third largest of the 23 pairs of chromosomes found in humans. It spans nearly 200 million base pairs, the building blocks of DNA, making up around 6.5% to 7% of the genetic ...

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 ...

Researchers have discovered how the MSL complex responsible for dosage compensation can distinguish the X chromosome from autosomes in flies. A lab used a unique research approach to determine the ...
