In order to ensure that only fully processed mature mRNAs are allowed to be exported to cytosol, pre-mRNAs associated with snRNPs are retained in the nucleus. To demonstrate this, an experiment was performed where a gene coding a pre-mRNA with a single intron was mutated either at the 5’ or 3’ splice sites or both the splice sites.
Given below are a few possible outcomes, Choose NOT FEASIBLE OUTCOME
A. Pre-mRNA having mutation at both the splice sites will be retained in the nucleus because of the presence of bound snRNPs.
B. Pre-mRNA having mutation at both the splice sites will be exported to cytosol because of the absence of bound snRNPs.
C. Pre-mRNA mutated at either 3’ or 5’ splice sites will be retained in the nucleus because of the presence of bound snRNPs.
D. Pre-mRNA mutated at either 3’ or 5’ splice sites will be exported to cytosol because of the absence of bound snRNPs.
