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.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
