Practice questions
- A patient with suspected urinary tract infection needs rapid, pathogen-specific testing. Which broad molecular diagnostic approach is specifically discussed as a means of detecting uro-pathogens more rapidly than conventional culture-based workflows?
- Genome analysis identifies a biosynthetic gene cluster in a microorganism, but its genes are transcriptionally inactive under routine laboratory conditions. Which approach is specifically recognized as a biological strategy to activate such a cryptic cluster?
- A laboratory has identified a silent biosynthetic gene cluster and wants to activate it by changing its transcriptional control. Which strategy named in reviews of cryptic gene-cluster activation most directly fits this goal?
- A genome-mining project identifies a biosynthetic gene cluster that is not expressed under ambient laboratory conditions. Which description best explains why it is termed cryptic or silent?
- An AI-based variant interpretation pipeline performs less reliably for a population whose genomes are poorly represented in the training data and reference resources. Which explanation is most appropriate?
- A research team studying molecular correlates of early adversity wants to examine an epigenetic measure highlighted in reviews of infant mental health research. Which measure is an epigenetic process?
- A preclinical study uses an animal model to investigate a human disease, but the findings translate poorly because of species differences. Which approach is identified as one way to improve human relevance in molecular biology research?
- A research group aims to discover and characterize products encoded by cryptic microbial biosynthetic gene clusters. Which overall strategy is most consistent with recent approaches described for improving such discovery?
