A human cell contains 46 chromosomes. To simplify our illustration, we'll show only four. Though the genetic code of a human being is contained within 46 chromosomes, only half of this number ...

Defects in this process can lead to cell death or diseases like cancer. A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into ...

The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious ...

Although the DNA code from cell to cell is the same ... coiling of chromatin (the thick line in this illustration). This coiling causes the chromosome to resemble a spring. Chromatin refers ...

One of the most powerful weapons that cancer cells have at their disposal is CIN, which involves randomly shuffling their chromosomes each time they divide. (See illustration on opposite page.) Errors ...

The diagram shows the relationship between the cell, its nucleus, the chromosomes in the nucleus, and genes. The order that these bases are found in the genes determines the order of the amino ...

It is the unit of heredity, and may be copied and passed on to the next generation. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and genes.

To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies.How the cell ...
