When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

Most mammals, including humans, have two sex chromosomes, X and Y. One sex chromosome is usually inherited from each parent, and they pair up as either XX or XY in every cell of the body. People with ...

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 ...

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 ...

When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

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 ...

Some cells can turn cancerous when they divide, due to chromosomes getting “lost” in the process. In a new study, researchers at the University of Warwick have uncovered what happens to these lost ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

“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 ...

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 ...
