A typical human cell normally contains 23 pairs of chromosomes, or 46 in total, and within these are four copies of 3.5 billion molecule base pairs of DNA.

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

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.

Any improvements in our abilities to image chromosomes would therefore be highly valuable." Each human cell, at metaphase, normally contains 23 pairs of chromosomes, or 46 in total.

Chromosomes come in a wide range of shapes across species and cell types, largely based on the size of each chromatin loop. Funabiki draws an example from the familiar (and frustrating) experience ...
