the packing ratio of DNA in metaphase chromosomes is approximately 10,000:1 (depending on the chromosome). This can be thought of as akin to taking a rope as long as a football field and ...

DNA is a mosaic of genetic fragments passed down through generations, but its clarity diminishes over time. While modern testing can trace ancestry through shared markers, the depth of this insight ...

A woman's egg cells are already formed in her body before she is born. However, with increasing age, DNA damage accumulates ...

The Homo sapiens genome today contains a little bit of Neanderthal DNA. These genetic traces come from almost every part of ...

DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of ...

At best, Cypriot men are 30 per cent of Greek descent, a study constructing the DNA reference of Cypriots has so far shown.

For years, the fact that women tend to outlive men has been a topic of interest and speculation among scientists and the ...

Transposons, or "jumping genes" - DNA segments that can move from one part of the genome to another - are key to bacterial ...

In the absence of DDM1 and RNAi, this TE doesn’t produce small RNAs, so the centromere is not methylated. These mutants also ...

Greenland sharks are thought to have lifespans that can reach 400 years. Building upon previous work, University of Tokyo-led ...

Transposons, or 'jumping genes' -- DNA segments that can move from one ... For one, inserting at the end of the chromosome helps the transposon avoid genes for the cell's core functioning, which ...

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro proof-of-concept study.
