Question
Chapter 13.3, Problem 1EQ
Summary Introduction
To determine: Whether the mex-3 mRNA corresponds to the sense strand or antisense strand in the given experiment.
Introduction: Fire and Mello conducted an experiment which showed that specific mRNAs are inhibited from translation by targeting them through a mechanism that uses a double-stranded RNA. Their experiment proved that for silencing mRNA, double-stranded RNA can be used instead of antisense RNA.
