Among the many marvels of life is the cell’s ability to divide and thus enable organisms to grow and renew themselves.

Centromeres, specialized regions located at the center of chromosomes, are critical for ensuring proper cell division. During mitosis, centromeres serve as assembly sites for complex protein ...

Ultrastructure of a condensed chromosome-like structure in a cyanobacterium Date: October 20, 2016 Source: National Institutes of Natural Sciences Summary: Eukaryotic cells, including human cells ...

Chromosomes hold an organism’s genetic blueprint in their DNA, but the DNA is just one part of a highly complex chromosomal structure involving many different proteins with different functions, from ...

When cells prepare to divide, their DNA is tightly wound around proteins to form chromosomes that provide structure and support for genetic material.

Frozen mammoth skin retained its chromosome structure Features as small as 50 nanometers preserved in a 50,000-year-old sample.

If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be ...

This reproduction process is referred to as cell division or mitosis. During mitosis, the parent cell will duplicate its chromosomes in order to pass down the genetic material to the daughter cells.

New findings shed light on how chromosomes manage the various pushing and pulling forces generated when cells divide. Specifically, researchers show that chromosomes resist being punctured by the ...

Inside the circle were genetic instructions to make a sturdier centromere—the “button” that keeps the chromosome structure intact and can make it replicate. Once expressed inside a yeast cell, the ...

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells. Researchers at RPTU have now investigated the detailed effects of such ...

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.
