Scientists Discover Why X Chromosome Lack Housekeeping Genes
Men have one copy, women have two, but scientists have long puzzled over why the human X chromosome mostly contains genes that are active in a small number of tissues. Now, a team of researchers led b...
Gene On-Off Switch Works Like Backpack Strap
A research team based in Houston's Texas Medical Center has found that loop-forming proteins inside the human chromosome appear to work like the sliding plastic adjusters on a grade-schooler's backpac...
New Findings Shed Light On Fundamental Process Of DNA Repair
Inside the trillions of cells that make up the human body, things are rarely silent. Molecules are constantly being made, moved, and modified — and during these processes, mistakes are sometimes made....

Genetic code
The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells. Biological decoding is accomplished by th...

Chromosome 5 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 5 spans about 181 million base pairs (the building blocks of DNA) and repre...
Azoospermia factor
Azoospermia factor (AZF) refers to one of several proteins or their genes, which are coded from the AZF region on the human male Y chromosome. Deletions in this region are associated with inability to...
Subtelomere
Subtelomeres are segments of DNA between telomeric caps and chromatin.
Telomeres are specialized protein–DNA constructs present at the ends of eukaryotic chromosomes, which prevent them from degra...

Deletion (genetics)
In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is missing. De...
