Summary Introduction

To review:

The importance of adding a toxin in the study that aimed to determine the speed of pre-mRNA (messenger ribonucleic acid) splicing in the cells.

Introduction:

In biology, splicing is the conversion of the nascent messenger RNA (pre-mRNA) transcript into a mature messenger RNA (mRNA). During splicing, introns (noncoding regions) are removed from the pre-mRNA and the mature messenger RNA contains only exons (coding regions).

Biologists have investigated how fast pre-mRNA splicing occurs by treating cells with a toxin that blocks the production of new pre-mRNAs, then following the rate of splicing of the pre-mRNAs that were transcribed before adding the toxin.
