4 Expert PromptsGenomic Variant Annotation and Prioritization
Given a VCF file containing 1000 genomic variants from a recent whole-exome sequencing study, use a combination of gene annotation databases (e.g., RefSeq, Ensembl) and functional prediction tools (e.g., SIFT, PolyPhen) to prioritize variants for further analysis based on their predicted impact on protein function and disease association. Provide a ranked list of the top 20 variants, including their genomic coordinates, gene symbols, and functional prediction scores, along with a brief description of the biological pathways and processes they are involved in.
Time-Series Analysis of Gene Expression Data
Using a dataset of gene expression levels measured at 10 time points over a 24-hour period, apply techniques from signal processing and machine learning (e.g., Fourier analysis, clustering, regression) to identify genes that exhibit periodic or oscillatory behavior, and characterize their expression patterns in terms of amplitude, phase, and frequency. Provide a list of the top 10 genes with the most significant periodic expression, along with their expression profiles and statistical summaries (e.g., mean, variance, autocorrelation), and discuss the potential biological implications of these findings in the context of circadian rhythm regulation.
Phylogenetic Tree Reconstruction and Comparative Genomics
Given a set of 50 protein-coding gene sequences from a diverse range of organisms, including bacteria, archaea, and eukaryotes, reconstruct a phylogenetic tree using maximum likelihood or Bayesian methods (e.g., RAxML, MrBayes), and analyze the resulting tree topology to identify patterns of gene gain, loss, and horizontal transfer. Provide a graphical representation of the phylogenetic tree, along with a table summarizing the gene content and functional categories of each organism, and discuss the implications of these findings for our understanding of evolutionary relationships and genomic innovation.
Metabolic Network Reconstruction and Flux Balance Analysis
Using a genome-scale metabolic model of a microorganism (e.g., E. coli, S. cerevisiae), reconstruct the metabolic network by integrating gene expression, proteomic, and metabolomic data, and apply flux balance analysis (FBA) to predict the optimal flux distributions and growth rates under different environmental conditions (e.g., carbon sources, nutrient limitations). Provide a graphical representation of the metabolic network, along with a table summarizing the predicted fluxes and growth rates, and discuss the potential applications of these findings for biotechnological optimization and synthetic biology design.
