Summary Introduction

To determine: The effect of changes in splicing on RNAs and function of a tumor-suppressor gene.

Introduction: The splicing of RNA refers to a method of RNA processing where a precursor messenger RNA gets transformed into a mature messenger RNA. The process of splicing excise introns from the exons during the process of splicing.

Summary Introduction

To determine: The ways by which the loss of splicing specificity can be associated with cancer.

Introduction: During the process of splicing the removal of introns from the pre-mRNA occurs, whereas the exons remain together and form mature mRNA. The encoding of the protein is only done by the exons.

lin-28 is a gene that is critical for stem cell integrity in mammals and is involved in tumourigenesis, but it was originally identified as a gene involved in developmental timing in C. elegans. It is targeted by the microRNAs lin-4 and let-7 and this affects its translation. Q2a) If the lin-4 sequence is 5’-UCCCUGAGACCUCAAG-3’, which of the following sequences might best correspond to the single target RNA sequence in the 3’UTR of lin-28.  A) 3’ UTR- 5’-UCCCUGAGACCUCAAG-3’ B) 3’ UTR- 5’-CUUGAAAUCUCAGUUA-3’ C) 3’ UTR- 5’-CUUGAGGUCUCAGGGA-3’ Q2b) Then describe in 2 sentences/lines why you chose this target sequence.
MicroRNA hsa-miR-155-5p targets mRNA that encode the genes JARID2 and KDM5B. In the cells of some cancers, hsa-miR-155-5p is downregulated – becomes less abundant. What would you expect to happen to the levels of the proteins JARID2 and KDM5B in the cancerous cells?
A mutant strain of Salmonella bacteria carries a mutation of the rho protein that has fully activity at 37°C but is completely inactivated when the mutant strain is grown at 40°C. a)Speculate about the kind of differences you would expect to see if you compared a broad spectrum of mRNAs from the mutant strain grown at 37°C and the same spectrum of mRNAs from the strain when grown at 40°C. b)Are all the mRNAs affected by the rho protein mutation in the same way? Why or why not?
