Question

NISUUS UU NI pui CIOS VIVIENZync. 20. (4 pts) You are performing an experiment on eukaryotic intron splicing and are trying to determine the mechanism by which a particular intron is spliced. You find that the primary transcript is spliced without presence of any protein. Based only on this information what can you conclude with confidence about this intron? (Check all that apply) It is an intron in mRNA. It is a Group I or Group Il intron. _It is not an mRNA intron. _It will require U1 and U2 RNAs in order to be spliced.

Answer 1

1912 Answers e answer to the question is the 2nd option - It is a brroup I or boroup II inmon e is because Group I and Group II untons eelf - splicing introns that can carry out enlucing reaction on their own without volvement of any other profeen or This is be are self- so the splicera o the envolvement numer per splicing machinery the other options cannot be the correct choice because option I says it is an intron en mRNA 7 but that does not gives the reason as how the splicing occured without any grotein and hence it eannot be correof choice. option 3 says it is not an mRNA intro beet this cannot be the case, because, it does not clarify the type of intron that self splice themselves.. " option 4 is clearly not possible, because will require u2 and ul SnRups for uch are the components of land is absolutely false in ording to the question splicing, which are the en spliecosome and is absolut this case according to the at Hence the night option is the 2nd one - It is a Group I or Group It iure

Splicing is a mechanism by which the introns or the non-coding regions of the mRNA are removed from a Pre RNA to form a mature RNA that contains only the exons,which is then translated to proteins.The correct option to the question along with reasons has been explained in the picture above.
