in which exons on different pre-mRNAs are ligated together. The existence of introns and differential splicing helps explain how new genes are created during evolution. Splicing makes genes more ...

Exons can be separated by intervening sections of DNA that do not code for proteins, known as introns. Following transcription, new, immature strands of messenger RNA, called pre-mRNA, may contain ...

Each mRNA transcript contains coding regions, known as exons, and noncoding regions, known as introns. They also include sites that act as signals for where splicing should occur, allowing the ...

Investigators in the laboratory of Gemma Carvill, Ph.D., assistant professor in the Ken and Ruth Davee Department of Neurology Division of Epilepsy/Clinical Neurophysiology, have discovered novel ...

Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts. RNA splicing is a cellular ...
