Quiz zum Vortrag
Eukaryotic mRNAs differ from prokaryotic mRNAs in what way?
- They occasionally undergo splicing.
- They contain a poly-A tail at the 5’ end.
- They use a different genetic code.
- They lack a cap.
- The 5' end of tRNA is a CCA sequence.
Which statement is not true regarding RNA processing?
- In eukaryotic cells, the mRNA does not require any chemical modifications, whereas in prokaryotic cells the polycistronic mRNA needs splicing before translation.
- The poly-A tail in the mRNA at the 3’ end helps in transportation from the nucleus to the cytoplasm and provides stability.
- The AAUAA sequence in the 3’ end of the immature mRNA molecule acts as a signal for chopping off and the addition of poly-A tail to form a mature mRNA.
- The capping process involves the addition of 7-methylguanosine to 5’ end of the mRNA.
- The addition of a cap at 5’ end of mRNA helps in starting the translation process and protects mRNA from nuclease attack.
Which type of linkage occurs with the addition of 7-methylguanosine to mRNA?
- 5’ to 5’ linkage
- 3’ to 5’ linkage
- 5’ to 3’ linkage
- 5’ to 1’ linkage
- 3’ to 1’ linkage
