Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...
Life can look very different in a mirror. DNA’s famous double helix normally has a right-handed twist, for example, but its reflection corkscrews the other way, forming a left-handed helix called ...
Researchers have reconstructed transcription in human mitochondria in unprecedented detail, revealing potential drug targets ...
Aging, neurological diseases and our bodies' stress response are all linked to the tiny power plants inside each cell known ...
In July 2022, the World Health Organization (WHO) announced that monkeypox was a public health emergency of international concern. And, as of early December 2022, more than 82,000 human monkeypox ...
As expected, accuracy also depended on whether the DNA polymerase retains a 'proofreading' functionality, which verifies (and if necessary removes) any mismatched nucleotides: a version of the enzyme ...
DNA holds our genetic blueprints, but its cousin, RNA, conducts our daily lives I n 1957, just four years after Francis Crick ...
The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria ...
In the latest shake-up for scientific dogma, research has demonstrated that eukaryotic cells can convert RNA sequences back into DNA, through a misunderstood, ‘error-prone’ polymerase. Historically, ...
