Question: Question: The RISC complex (RNA-induced silencing complex) of RNA silencing based on interference RNA: 
 Options:  <1> It degrades the guide strand of the small interfering RNA molecules (siRNA). <2> It recognizes defective proteins and promotes their degradation. <3> It has a structure similar to the ribosome, formed by numerous RNAs and proteins. <4> It is formed, among others, by the Dicer protein, a type III ribonuclease. <5> It is part of both the interference mechanism of the siRNA and the microRNA.

Answer: 5


Question: Question: Liquid chromatography using linked stationary phases can be divided into normal phase and reverse phase phases. In this context it can be said that: 
 Options:  <1> The main separation mechanism in reverse phase is the distribution, while adsorption also plays a very important role in the normal phase. <2> In normal phase chromatography, a large number of non-polar stationary phases can be used. <3> The main separation mechanism in normal phase is the distribution, while the adsorption plays a very important role in the reverse phase. <4> In reverse phase chromatography, the stationary phase is polar and the non-polar eluents. <5> In reverse phase chromatography, a large number of polar stationary phases can be used.
