Which of the following are functions of the 5' cap (7-methylguanosine) on transcripts? (check all that apply) Helps microRNAs (miRNAs) regulate the transcript Facilitates recognition by proteins that initiate translation. Terminates the transcription process by causing RNA polymerase to fall off the template DNA Protecting the RNA molecule from degradation.

The functions of the cap on mRNA include: - mRNA splicing - Translational start identification - Addition of the poly(A) tail - RNA transcript protection from degradation - Identification of translation start site

What is the function of the 3' polyA tail on eukaryotic mRNAs? - Protect mRNA from 3' exonucleases - Promote loading of ribosome onto mRNA - Enhance export of mRNA out of the nucleus - Increase the rate of transcription elongation of the mRNA Which of the following reactions are catalyzed by RNA, rather than protein? - Peptide bond formation during translation - Phosphodiester bond formation during transcription - Splicing - Polyadenylation Which of the following is true of the 3' polyA tail on eukaryotic mRNAs? - The cap is synthesized by a polyA polymerase - The 3' polyA tail is added after the transcript is separated from the RNA polymerase - The polyadenylation signal sequence templates the synthesis of the tail - The tail is attached backwards through a 3'-3' linkage
