Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female ...

SciShow is supported by Brilliant.org. Tiny versions of chromosomes show up in things like birds, reptiles, and amphibians.

In a milestone achievement, a whole chromosome has been created from scratch by scientists for the first time ever. The tRNA Neochromosome is a man-made chromosome of the common baker's yeast ...

Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

Yale scientists have discovered a new potential treatment avenue to fight cancer. Using CRISPR gene-editing, the team eliminated extra chromosomes from cancer cells and found that they could no longer ...

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 ...

In most mammals, females have two X chromosomes and males have one X and one Y chromosome in each of their cells. To avoid a double dose of X-linked genes in females, one of the Xs is silenced early ...

Sex chromosomes must exchange genetic information at a short region during meiotic cell division. Molecular factors have now been found that alter sex-chromosome structure and enhance this exchange ...

Triploidy is a condition that affects 1% to 3% of pregnancies. It’s when a developing baby has an extra set of chromosomes, the thread-like structures that carry DNA. A triploidy pregnancy usually ...

“We’ve known that tiny fragments of ancient DNA can survive for long periods of time,” said Dr. Marcela Sandoval-Velasco of the Center for Evolutionary Hologenomics at the University of Copenhagen and ...
