A new analysis of ancient DNA has found that Neanderthal genomes contain 62 percent more ancestry from anatomically modern ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Systemic lupus erythematosus (SLE), the most common form of lupus, is an autoimmune disorder that occurs more frequently in ...

Cell division is a process of remarkable precision: during each cycle, the genetic material must be evenly distributed between the two daughter cells. To achieve this, duplicated chromosomes, known as ...

Merotelic kinetochore (single kinetochore attaches to microtubules from two spindle poles) has been proposed to be the major mechanism underlying the spontaneous formation of lagging chromosomes, ...

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 ...

The first theoretical model of condensin, a molecular machine involved in packing and unpacking chromosomes, accurately reproduces all known experiments with just two parameters. To scrunch a ...

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 ...

Humans contain 46 chromosomes (23 from their mother, and 23 from their father) in each of their body cells. This image shows duplicated chromosomes from a human male. Summary Scientists at the Sloan ...
