With so many at-home DNA tests now available to consumers, learning more about your ancestry is easier than ever. Plus, these tests make for thoughtful, unique holiday gifts. All you have to do is ...

Our genes, sections of DNA that code for different proteins, have a set of switches and levers that tell them how to express themselves, known as epigenetics. As part of this system, there are markers ...

Genetic markers are DNA sequences with known physical locations on chromosomes. They are points of variation that can be used to identify individuals or species, or may be used to associate an ...

DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

It started with a finger bone found in a cave in the Altai mountains in Siberia in the late 2000s. Thanks to advances in DNA analysis, this was all that was required for scientists to be able to ...

and the DNA sizes were compared with those of Marker L (50–5,000 bp) (Sangon Biotech, China). Ultraviolet light was used to detect the bands. Original RNA (2 μg) was added to 2U RNase R (GeneSeed, ...

This set of changes would therefore match the increased demand for both ATP and metabolites that is required for DNA and protein synthesis in these rapidly proliferating effector T-cells. Taken ...

This paper presents the important discovery that lipid metabolic imbalance caused by Snail, an EMT-related transcription factor, contributes to the acquisition of chemoresistance in cancer cells.
