The siRNA and miRNA pathways share many similarities and also have some differences. Which of the following is true about these two noncoding RNA classes in regulating gene expression? O Both of them utilize the internally generated RNAS as sources to produce the short regulatory RNAS Both of them need Dicer to process the long RNAS into short double-strnaded RNAS Both of them required perfect match between the short noncoding RNAS to the mRNAS Both of them end up with complete degradation of the target mRNAS

RNA-mediated interference is a post-transcriptional gene silencing mechanism. Which component(s) of the RNAi pathway have been implicated in the endonucleolytic cleavage of the target mRNA? Choose one. - Dicer enzyme - the RISC complex - the Drosha complex - the Exosome - XRN1

Select all the examples of mutations that are likely to have a global effect on gene expressio

Which of the following is NOT true about cis-regulatory elements (CREs)? Group of answer choices Enhancers, silencers and promotors can be located anywhere in relation to the gene Enhancers are involved with increasing gene expression CREs often contain motifs that allow transcription factors to bind CREs are involved in determining the timing, location and amount of gene expression
