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 cell's nucleus contains chromosomes. These are long threads of DNA, which are made up of many genes. Humans have around 25,000 genes across their 23 pairs of chromosomes.

Small sections of the chromosome, called genes, code for the ... all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA ...

except that in this cell the chromosomes attach to the membrane of the nucleus and then pair up with their corresponding chromosome. While paired up, enzymes cut sequences of DNA (genes ...

A study described the three-dimensional architecture of turtle genomes, which fold in a configuration unlike any other animal observed so far.

it currently has around 900 genes compared to the Y chromosome's meagre 55. So why has the male-determining chromosome been shrinking? And what does this mean for the future of men and humankind as a ...

New research finds that turtle genomes show a chromatin arrangement that hasn't been observed in other organisms.
