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 ...

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 ...

DNA holds our genetic blueprints, but its cousin, RNA, conducts our daily lives I n 1957, just four years after Francis Crick ...

Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA and RNA. PCR involves the enzymatic amplification of ...

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 ...

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, ...

Promega files patent for first-of-its-kind enzyme that minimizes stutter artifacts in STR analysis Reduced stutter polymerase enhances accuracy, efficiency and reliability of DNA profiling in forensic ...
