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 some genes, not all of the DNA sequence is used to make protein. Introns are noncoding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is ...

A research team from Whitehead Institute has uncovered a surprising and previously unrecognized role for introns, the parts of genes that lack the instructions for making proteins and are typically ...

Introns and exons are nucleotide sequences within a gene. Introns are removed by RNA splicing as RNA matures, meaning that they are not expressed in the final messenger RNA (mRNA) product, while exons ...

Spliceosomal introns are noncoding DNA sequences located between exons in many eukaryotic protein-coding genes. Most are removed post-transcriptionally by RNA splicing and do not encode proteins, but ...

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 ...

Our genome contains the genes that code for the proteins that carry out most biological functions, as well as a lot of other sequence. Some of that other sequence serves various regulatory roles, and ...

An Arabidopsis loss-of-function study links the mitochondrial PPR9 protein to impaired RNA splicing, defective respiratory complex I assembly and arrested early embryonic development.

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 ...

Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have self-splicing RNA introns. The RNA transcript of such a gene can carry out the entire ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...
