Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one X and one Y chromosome. According to Medline Plus, in every cell, humans ...

That changed in 2014, when Swedish scientists showed that Y loss in blood cells correlates with how long men live – those who ...

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

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 ...

Iowa State University researchers have unlocked new secrets within the bacteria responsible for the creation of thousands of ...

Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males from ...

The Atlas blue butterfly, with a record-breaking 229 pairs of chromosomes, is helping scientists unravel mysteries of ...

Chromosomes in egg cells within fetal ovaries must be spliced and sorted perfectly. A new landmark study from UC Davis shows how protecting Holliday junctions allows this to happen.

In this episode of Tiny Show and Tell Us, we cover the science of rainbows and why double rainbows are always mirror images. Then we talk about mysterious, yet super common, chromosomes called ...

Translocations, in genetics, happen when chromosomes break and the pieces attach to other chromosomes. This mixing of genetic material has important results. The resultant chromosomes are lacking in ...

Scientists have confirmed that the Atlas blue butterfly carries the most chromosomes of any animal, with 229 pairs. Unlike duplication, its chromosomes split apart, reshaping its genome in surprising ...

New research by UCLA Health has identified a sex-chromosome linked gene that drives inflammation in the female brain, ...
