Which eukaryotic RNA polymerase (RNA pol I,pol II, or pol III) transcribes which genes?a. tRNAsb. mRNAsc. rRNAsd. miRNAs

Which of the following about the splicing in posttranscriptional processing is NOT true? a. In bacterial, the genes coding for polypeptides are interrupted by non-coding regions. O b. O C. O d. Introns in eukaryotic hnRNA must be cut out before mature mRNA can be used for protein synthesis. Alternate splicing can lead to tissue-specific proteins. Splicing can lead to multi-domain proteins.

Differential RNA splicing may result in: a. A shift in the ratio of mRNA produced from two neighboring genes b. Inversion of exons in the mature mRNA c. Production of the same protein from two different genes d. Production of two different proteins with different properties from a single gene
