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 ...

Introns that elevate mRNA accumulation have been found in a wide range of eukaryotes. However, not all introns affect gene expression, and direct testing is currently the only way to identify ...

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 ...

During the process of transcription, DNA is converted to RNA, a complex molecule that is able to carry genetic information outside of the cell's nucleus. This page guides you through the biochemical ...

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 ...

Researchers have shown for the first time that non-coding parts of genes called introns can copy themselves and move around the genome. Nevertheless, these DNA sequences remain mysterious. Scientific ...

BLOOMINGTON, Ind. -- The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to a recent Science report by Indiana ...

The genomic clones containing elements that regulate transcription of the three known rice (Oryza sativa L.) alpha-tubulin isotypes (Ostua1, Ostua2 and Ostua3) have been isolated. We have used these ...

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 ...

The authors made their discovery when they spotted an in-frame stop codon in a G. lamblia sequence that encodes the iron-carrying protein ferredoxin in the results of a BLAST search. Could this stop ...
