Protein-coding genes carry the blueprint for protein production. In higher organisms, however, most of the coding-gene transcripts, or pre-mRNAs, are separated by non-coding sequences called "introns, ...

The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to researchers. Their study of the model organism Daphnia ...

In a recent study of genes involved in brain functioning, their previously unknown features have been uncovered by bioinformaticians from the Moscow Institute of Physics and Technology and the ...

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots ...

Researchers have long puzzled over why many eukaryotic protein-coding genes are interspersed with segments of noncoding DNA that have no obvious biological function. These so-called introns are ...

One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...

So you probably know organisms carry DNA, which is basically a set of instructions for how to build and operate the body. The nucleus of every cell carries the genome, which contains those genes, as ...

Pre-mRNA splicing in a subset of human short introns is governed by a distinct mechanism involving a new splicing factor, new research finds. The interrupted non-coding regions in pre-mRNAs, termed ...

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots ...

The interrupted non-coding regions in pre-mRNAs, termed “introns,” are excised by “splicing” to generate mature coding mRNAs that are translated into proteins. As human pre-mRNA introns vary in length ...
