Which of the following levels of control involves the use of a poly-A tail?
A) pretranscriptional
B) transcriptional
C) posttranscriptional
D) transcriptional control
E) translational
Poly-A Tail
A stretch of adenine nucleotides added to the 3' end of mRNA molecules, protecting the mRNA and aiding in its export from the nucleus.
Transcriptional
Pertaining to transcription, the process by which genetic information from DNA is copied to RNA, leading to protein synthesis.
Posttranscriptional
Pertaining to modifications and processes that occur in a eukaryotic cell after transcription of DNA into RNA, affecting mRNA stability, translation, and other aspects.
- Discuss the modulation of gene expression through different segments, including transcriptional, posttranscriptional, translational, and posttranslational processes.
