Around 8 percent of human DNA is made up of genetic sequences acquired from ancient viruses. These sequences, known as human endogenous retroviruses (or Hervs), date back hundreds of thousands to ...
It's long been assumed that as cells divide in the human body, the genome is faithfully replicated in the resulting daughter cells. While errors are known to arise, there is machinery in the cell that ...
Most fat stores energy; the body's brown fat does the opposite. Unlike the white fat that accumulates just under our skin, ...
Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ...
Researchers have unveiled a new biological platform for studying mitochondrial DNA in physiology, adaptation, disease ...
The human immune system is finely tuned to detect and destroy viral threats. But this same defense system can misfire. When ...
DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...
