Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Sturtevant illustrated the crosses and offspring resulting from a parental strain of gray-eosin female flies and yellow-red male flies. He followed this cross to the F2 generation. How would you feel ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

The Atlas blue butterfly, also known as Polyommatus atlantica, has been genetically confirmed as having the highest number of chromosomes out of all multicellular animals in the world. Subscribe to ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

A microscopic piece of genetic material known as the Y chromosome made headlines last week. It is nothing new or rare; every man has one in practically every cell, or he would not be a man. But a few ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Now, ...

Highly challenging to sequence and long overlooked, the human Y chromosome's contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...

The Atlas blue butterfly, also known as Polyommatus atlantica, has been genetically confirmed as having the highest number of chromosomes out of all multicellular animals in the world. This insect ...
