Input: Consider Input: 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.

Input: Consider Input: Question: A 52-year-old woman is detected on a mammogram by a nodule and is advised to perform a biopsy by puncture with ultrasound control. The patient asks you about the probability of having cancer if the test comes out positive. Since you have no experience in this area, you are looking for and find a study that includes 112 patients, 18 with cancer and 94 without cancer. Of the 18 patients with cancer, the puncture gave a positive result in 16 and of the 94 patients without cancer the puncture gave a negative result in 88. With these data the correct answer is: 
 Options:  <1> 0,727. <2> 0.93. <3> 0.645. <4> 0.56. <5> It can not be calculated because the prevalence of the disease is not known.
