Silencing - Study guides, Revision notes & Summaries

1. The medical-surgical nurse identifies a clinical practice issue and wants to determine if there is sufficient evidence to support a change in practice. Which type of study provides the strongest evidence to support a practice change? 1) Randomized control study 2) Quasi-experimental study 3) Case-control study 4) Cohort study 2. The medical-surgical unit recently implemented a patient-centered care model. Which action implemented by the nurse supports this model? 1) Evaluating care 2)...

When does RNA-mediated gene silencing occur? correct answers After transcription of an mRNA but before translation What is gene silencing? correct answers When RNA interferes and prevents protein synthesis through base pairing between ncRNA and mRNA. What is NOT part of translational termination? correct answers Uncharged tRNA recognition of stop codon in the mRNA Which type of interaction is NOT a functional mechanism by which IncRNA regulates gene expression? correct answers IncRNA ca...

What is Methylation? Ans: addition of methyl groups (CH3) to specific DNA nucleotides What performs methylation? Ans: DNA methyltransferases, add primarily to Cytosine bases What bases are primarily methylated? Ans: Cytosine - located in CpG dinucleotides What is a CpG dinucleotide? Ans: side by side Cytosine and Guanine nucleotides in same DNA strand What part of DNA is mostly methylated? Ans: In eukaryotic genomes, most methylated DNA is found in transposable elements and non-coding...
