Trisomy is a genetic condition characterized by the presence of an extra chromosome. This means that the affected person has ...

The nucleus of every human cell contains chromosomes—23 pairs, to be exact. These carry our genetic material, known as the genome, and are composed of deoxyribonucleic acid (DNA) and proteins.

Scientists in Japan have used gene-editing technology to remove the extra chromosome responsible for Down syndrome, at least ...

Every healthy human cell contains 23 pairs of chromosomes, which must be duplicated and distributed evenly between two daughter cells during a process known as cell division.However, if something ...

Researchers at the IPK Leibniz Institute have discovered a previously unknown protein that is central to plant reproduction.

This iron buildup is harmful because it triggers oxidative stress, a process that damages cells by producing toxic molecules.

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

A new paper describes how scientists used the tool to identify an important role for TRIM24 in mediating telomere repair after cells divide.

Each time a cell divides, a small section of each chromosome's protective cap — the telomere — is worn away. Most cells use ...
