The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Chromosomes are a highly condensed form of DNA and are crucial for cell division. During mitosis, chromosomes ensure that the genetic material is equally divided among the daughter cells.

DANVILLE, Pa. – A Geisinger study provides new insight into height differences between adult men and women, demonstrating that Y chromosome genes contribute more to height than their X chromosome ...

A new study challenges prevalent models of chromosome formation during mitotic cell division. The study compared the dimensions of chromosomes in yeasts and humans and found that not only is the width ...

The 23 rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

This video segment from NOVA: "Judgment Day: Intelligent Design on Trial" reveals how genetic evidence helped to confirm an important component of Darwin's theory of evolution by natural selection: ...

Mitotic chromosomes are pivotal for the inheritance of genetic material. Now, it is already known that chromosomes vary in dimensions among organisms. But what governs mitotic chromosomal size and ...
