Telomere
A telomere is a region of repetitive nucleotide sequences at each end of a chromatid, which protects the end of the chromosome from deterioration or from fusion with neighbouring chromosomes. Its name...

Malaria beats immune system by causing it to self-sabotage
The malaria parasite infects the body by influencing the immune system to take self-sabotaging actions, making the pathogen's path through the body easier.
Biologists Unravel Drug-Resistance Mechanism In Tumor Cells
About half of all tumors are missing a gene called p53, which helps healthy cells prevent genetic mutations. Many of these tumors develop resistance to chemotherapy drugs that kill cells by damaging t...
Beyond Genes: Are Centrioles Carriers Of Biological Information?
Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad r...
Caffeine + alcohol keeps your chromosomes just right
The ends of your chromosomes are sensitive to a variety of environmental factors.
Mitosis
Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus. In general, mitosis (division of the ...

Non-homologous end joining
Non-homologous end joining (NHEJ) is a pathway that repairs double-strand breaks in DNA. NHEJ is referred to as "non-homologous" because the break ends are directly ligated without the need for a homo...
