RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, ...

To do this, this large protein-RNA complex, which is located in the cell nucleus, removes non-coding sections (introns) from mRNA precursors and links the coding sections (exons) to form a ...

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 ...

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 ...

and the noncoding sections interspersed among the exons are known as introns. During splicing, which occurs after transcription (i.e., the synthesis of RNA from a DNA template), the introns are ...

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 ...

Splicing is a processing event in which non-coding segments called introns are removed from immature mRNA and the coding segments (exons) are joined together to form a mature mRNA (Fig.

Les différentes étapes de cette synthèse sont l'initiation, l'élongation et la terminaison. Le processus de synthèse des ARN est sensiblement différent chez les organismes procaryotes et chez les ...
