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 ...

Researchers at Moffitt Cancer Center have developed a new way to predict how cancer cells evolve by gaining and losing whole ...

Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Scientists first read the human genome, a three-billion-letter biological book, in April 2003. Since then, researchers have steadily advanced the ability to write DNA, moving far beyond single-gene ...

Every human cell has a pair of chromosomes that give your body a blueprint for how to grow and develop starting as a single cell inside a uterus. But in a new study from the Cedars-Sinai cancer center ...

Mosaic trisomy 8 is a rare genetic condition caused by an extra chromosome. Sometimes called trisomy 8 mosaicism, this condition develops well before birth. It's a result of an abnormality in how ...

Researchers from Tokyo Metropolitan University have developed a suite of algorithms to automate the counting of sister ...
