What are the roles of 3' and 5' untranslated regions in mRNAs?
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?

3. RNA splicing. Eukaryotic mRNAs are frequently spliced before they are translated. Algae have the smallest known intron. The sequence of the algal pre-mRNA before splicing occurs is shown below. exon 1 intron exon 2 5-AUGGAAAUUAAGUACUAUAUUGAAUUUCAGGUUGAAGAUUUAGGAAUGG-3' A) What is the sequence of the mature mRNA after splicing occurs? 5'- -3' B) What is the sequence of the polypeptide after translation occurs?

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...
