Which of the following processes occurs in eukaryotic gene expression?

RNases and proteases are enzymes that destroy RNAs and proteins, respectively. Which of the following enzymes, if added to a spliceosome, would be predicted to prevent recognition of pre-mRNA regions critical for splicing?a. an RNase specific for tRNAsb. an RNase specific for snRNAsc. a protease specific for initiation factorsd. a protease specific for a release factor

Would the coupling of the processes shown in Figure 17.24 be found in a eukaryotic cell? Explain why or why not.

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. Why is addition of a toxin important in this study?

In eukaryotes, which mechanism operates after transcription, but before translation of mRNA into protein?

Which accurately describes the usual process of eukaryotic transcription?
