What's the difference between mRNA and pre-mRNA? It's all about splicing of introns. See how one RNA sequence can exist in nearly 40,000 different forms. Next, the snRNPs U2 and U4/U6 appear to ...
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 ...
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 ...
Researchers at University of Tsukuba have decoded the nuclear genome of Amorphochlora amoebiformis, a unicellular marine alga ...
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 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 ...
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 ...
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 ...
