, MFT: Cell Biology Exam Questions And
Answers
Post-transcriptional modification -
correct answer ✅the modifications that occur to an mRNA
transcript before it is exported from the nucleus as mature mRNA.
Include: splicing of introns, addition of 5' cap, addition on poly-A-
tail and rearranging of exons
Ubiquitination -
correct answer ✅targets a protein for degradation by a
proteasome + example of a post-transcriptional modification
Transmembrane insertion -
correct answer ✅an integral membrane protein that spans the
phospholipid bilayer
Function of enzyme -
correct answer ✅lower the activation energy for reaction by
enabling reactants to come together more easily
What regulates enzymes? -
correct answer ✅inhibitors
