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.

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, ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 ...

The images above depict artificially-derived neurons grown in petri dishes, with a human neuron shown on the left. Artificially-derived chimpanzee neurons grow only one or two neurites (connecting ...

They contain half the number of chromosomes of other human cells (somatic cells contain 46 chromosomes, but egg and sperm cells have only 23, since they combine their genetic payloads during ...

Human Chromosomes Evolved at Hyperspeed to Give Us Better Brains A study of artificial human and chimpanzee nerve cells revealed how faster-evolving DNA gives neurons the ability to build ...
