DNA could be one in a million possible genetic molecules

Saturn's moon Enceladus, where we hope there are aliens. Image : NASA / JPL-Caltech / Space Science Institute [19659004] According to a recent article, there could be a million different structures that can store genetic information. DNA stores the genetic information that describes the entire life of the Earth in the form of a twisted framework that is lined with …

In order to survive in the human gut, bacteria need a genetic "passcode"

Abstract Bacteria need a number of specialized genes to live in the human gut – and the composition of these genes varies from person to person. Therefore, efforts may need to be made to improve the health of the microbiome, including next-generation probiotics. The human gut is a dangerous place to exclude toxins to deter microbial invaders. However, every human's …

Hidden genetic variations power evolutionary leaps

Credit: CC0 Public Domain              Laboratory populations that quietly amass 'cryptic' are known as evolutionary leaps, according to a paper in the July 26 issue of Science . A better understanding of cryptic variation may improve the development of techniques for developing new biomolecules for medical and other applications.                                                 Genetic variation-that is, accumulated mutations in the DNA is the …

Convergent Development: Neanderthal and woolly mammoths may share common genetic traits

A new study from Tel Aviv University suggests that the genetic profiles of two extinct mammals of African descent – woolly mammoths, elephant-like animals that evolved on the Arctic Peninsula of Eurasia about 600,000 years ago, and Neanderthals, highly skilled early humans, that evolved early Developed in Europe about 400,000 years ago – common molecular characteristics of adaptation to cold …

FDA Warns Virginia Lab against Illegally Marketing Unproven Genetic Testing

Copyright: AP A series of genetic tests designed to predict a person's response to certain drugs is being developed by their manufacturer, Inova Genomics illegally markets Laboratory because the tests are not supported by scientific data, claims the US Food and Drug Administration. The FDA yesterday sent a warning letter to Inova, advising the Virginia-based medical company not to market …

Scientists call for a ban on genetic modification in humans – BGR

It has been months since Chinese geneticist He Jiankui announced to the world that he has genetically modified human embryos that were then born and gave birth to twin girls. His work, which was heavily criticized from all corners of the scientific community, put him in custody and could even face the death penalty if all is said and done. …
