NASA Ames reproduces the building blocks of life in laboratory
NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample containing ...
Squid enrich their DNA 'blueprint' through prolific RNA editing
One of the surprising discoveries to emerge from the young field of comparative genomics is that drastically different organisms—humans, sea urchins, worms, flies —are endowed with a more or less common ...
Statistician helps resolve dispute about how gene expression is controlled
The differences between different tissues, such as brain and muscle, and between healthy and unhealthy human cells are largely defined by changes in the abundance of proteins in the cells. Transcription—the ...
Researchers devise new method to identify disease markers
UCLA life scientists have created an accurate new method to identify genetic markers for many diseases—a significant step toward a new era of personalized medicine, tailored to each person's DNA and RNA.
New mitochondrially-derived peptides show what they can do
How genes are permanently silenced by small RNAs
Marc Bühler and his team at the Friedrich Miescher Institute for Biomedical Research (FMI) have elucidated the mechanism underlying small RNA-mediated gene silencing, thus solving a mystery which has been ...
Researcher develops novel strategy to improve crops and treat diseases
A novel strategy to enhance genome editing promises to increase the efficiency of making genetic improvements in a wide range of organisms, a new study suggests.
New research characterizes novel aspects of maize reproduction
Male reproductive organ development in maize involves a complex array of ribonucleic acid molecules (RNAs) with potentially diverse activities in gene regulation, demonstrated by new research from the University ...
Discovery holds promise for gene therapy and agriculture
A fundamental question pursued by plant scientists worldwide for the past decade has been answered by researchers led by the University of Sydney.
Rather than being a one-way street, DNA-directed RNA transcription may have profound adaptability
The central dogma of molecular biology describes the flow of genetic information. It was first described by Francis Crick in 1956 as one-way traffic: as: "DNA makes RNA and RNA makes protein."
