QUESTION 42 This is incorrect with respect to RNA: A. In eukaryotes, mRNAs are monocistronic (.e., they encode only one gene). B. In eukaryotes, messenger RNA is translated in the ribosome after having several post-transcriptional modifications. C. NO RNA molecule is capable of forming secondary structures le, double stranded regions), D. In prokaryotes, mRNAs are polycistronic (1.0., they encode several genes).

What are “cis-regulatory elements,” “trans-regulatory factors,” “exons,” “introns,” “untranslated regions,” “proximal promoters,” “enhancers,” “repressors,” "activators,” “caps,” and “poly-A tails”? Which are protein coding sequence (or are actual proteins); which are not? Which make it into mature mRNA?

What is the major difference between the removal of introns in animal pre- mRNAs and removal of group II introns from pre-mRNAs: 1. In animals, many snRNPs are needed to carry out the splicing 2. In animals, the introns do not self-splice 3. In animals, the introns are self-splicing 1 2 Both 1 and 3 are correct Both 1 and 2 are correct What causes unequal crossing over? Sections of the chromosome are replicated spontaneously. Pieces of chromosomes are translocated...

A point mutation within what functional part of a DNA sequence would be most likely result in the production of a protein that differs from the non-mutated form by only a single amino acid? a.Promoter b.5’ or 3’ Untranslated regions c.Exons d.Introns What if the mutation prevented transcription? What if the mutation prevented the mRNA from exiting thenucleus?
