Humans inherit one set of chromosomes from their mother and a second set from their father. In total, most human cells contain 46 chromosomes with 22 pairs of autosomes, or non-sex chromosomes ...

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.

During meiosis, the cell division process central to sexual reproduction, all chromosomes must figure out where to destroy ...

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 ...

Specialized protein machines called SMC complexes (Structural Maintenance of Chromosomes) play a critical role in these ...

Many genes may be transferred between chromosomes. Such translocation mutations can cause disorders of growth, development, and function of the body's cells and systems. Human cell nuclei have 23 ...

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

Now that certain human disorders have been linked with chromosome abnormalities, it is desirable to examine large numbers of cells for such abnormalities. A computer regime has been devised for ...

Each cell with a nucleus contains chromosomes, which are made from DNA Human body cells each contain 23 pairs of chromosomes, half of which are from each parent. So, human gametes (eggs and sperm ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...
