An international team of scientists have discovered ancient fossil chromosomes preserved in a glass-like state in the skin of a 52,000 year old female woolly mammoth, revealing a treasure trove of ...
The DNA in the mammoth sample fragmented but did not disperse: the pieces ran into a rare molecular traffic jam, so they hovered in place, keeping intact chromosome structures as tiny as 50 ...

More than 10,000 years ago, mammoths once roamed Texas. Herds of these lumbering, small-eared giants — called Columbian mammoths — with their long, curved tusks were a likely sight to behold ...
They used a method called High-Throughput Chromosome Conformation Capture Technique (Hi-C), which allows scientists to detect sections of DNA that sit close to each other in modern samples ...
How did early biologists unravel this complex dance of chromosomes? The most obvious difference between interphase and mitosis involves the appearance of a cell's chromosomes. During interphase ...
The 23 rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

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 ...
Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...
The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...
