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.
Cell cycle
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. In cells without a nuc...
Reverse transcription polymerase chain reaction
Reverse transcription polymerase chain reaction (RT-PCR) is one of many variants of polymerase chain reaction (PCR). This technique is commonly used in molecular biology to detect RNA expression. RT-...

Constitutive heterochromatin
Constitutive heterochromatin domains are sections of DNA that occur throughout the chromosomes of eukaryotes, but particularly at the centromeres, telomeres and repetitive sequences. They often consis...

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...

Long non-coding RNA
Long non-coding RNAs (long ncRNAs, lncRNA) are non-protein coding transcripts longer than 200 nucleotides (Perkel 2013). This somewhat arbitrary limit distinguishes long ncRNAs from small regulatory ...
Cell division
Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of...
