It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells.

The nucleus of every human cell contains chromosomes - 23 pairs, to be exact. These carry our genetic material, known as the genome, and are composed of deoxyribonucleic acid (DNA) and proteins.

Male smokers might want to start worrying about the tiniest and “manliest” of the 46 chromosomes — the Y chromosome. A new study published today in Science indicates that men who smoke ...

The Y chromosome is passed down exclusively from father to son. University of Arizona The human sex chromosomes, X and Y, evolved over the past 300 million years from the other, non-sex chromosomes.

Page agreed. "The Y chromosome has many more tricks up its sleeve than it was given credit for," he said. There are a couple of reasons Page and Hughes cite for Y being such an evolutionary ...

The Y chromosome has seen significant changes over the course of human evolution. "In comparison to the X, the Y is tiny. There are only 45 genes on the Y chromosome, ...

A few millennia could see disappearance of the Y chromosome, researchers say. July 17, 2009— -- What makes a man a man? Socially, that is a complicated question. Genetically, however, it is ...

Scientists fully sequence the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other issues.

A chromosome is a single, long molecule of DNA. These highly organized structures store genetic information in living organisms. Small sections of the chromosome, called genes, code for the RNA ...

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a ...

The Y chromosome, along with the X chromosome, is often discussed for its role in sexual development. While these chromosomes play a central role, the factors involved in human sexual development are ...
