3
Exam 1 material
  • Genomes sequences

4
Genomics
  • How are genomes sequenced?
  • What are the challenges in sequencing?
  • What kinds of large-scale functional features are
    found in genomes?
  • How is similarity visualized for large genomic
    regions?

5
Sequence alignment
  • Know what approaches are used to align sequences
  • Be able to score a given alignment
  • Be able to conduct a local and/or global
    alignment via a dynamic programming matrix
  • Understand how alignment approaches differ when
    using DNA versus amino acid sequences (e.g., PAM
    matrices)

6
Multiple Sequence Alignment
  • Know the basics of how BLAST works and how
    results might be interpreted
  • Understand conceptually why people are interested
    in conducting multiple sequence alignments
  • Know how to create a sequence profile score a
    multiple alignment

7
Phylogenetics
  • Know how to interpret a given phylogenetic tree
  • Be able to construct a phylogenetic tree

8
Genome comparison diversity
  • Understand the different ways SNPs can impact
    phenotype
  • Whats more likely to have an impact SNP in
    coding sequence or SNP that changes a splice site?

9
Exam 2 material
  • Genes and transcription

10
Gene finding
  • Prokaryotes
  • How are genes located in prokaryotes?
  • What type of gene finding systems are there?
  • Eukaryotes
  • How do gene finding approaches differ between
    eukaryotes prokaryotes?
  • How would you calculate specificity and
    sensitivity given a prediction from some gene
    finding program?

11
Alternative Splicing
  • How are genes alternatively spliced?
  • What are the evolutionary advantages of having an
    alternative splicing system?
  • How would a microarray detect alternative splice
    variants?

12
Microarray Analysis
  • Technology
  • Technology for measuring transcription
  • Image processing whats done, why, and
    advantages/disadvantages
  • Normalization what is it, what kinds of data
    are normalized, what kinds of methods are used
    for normalization?
  • Analysis
  • Clustering goals methods
  • Analysis of gene lists in terms of their
    biological meaning/significance
  • Genetic networks, what are they and how are they
    being approximated computationally?

13
RNA 2ndary structure
  • How does one identify secondary structure?
  • General strategies for trying to calculate
    secondary structures

14
Exam 3 material
  • Proteins Structure, function and interactions

15
Proteomics
  • Be familiar with techniques used to detect
    changes in protein levels and techniques used to
    identify what proteins are in a given sample

16
Protein Domains
  • Understand what protein domains are
  • Understand how they can be detected
  • Understand how they can be predicted

17
Protein 3D Structure
  • Know how one would go about predicting a 3D
    protein structure
  • What are some of the assumptions in predicting 3D
    structure

18
Protein-Protein Interactions
  • Be familiar with the basics of the technologies
    used to detect PPIs
  • Know the different structures that a network can
    have and what these structures imply in terms of
    their behavior
  • Remember some of the basics that we talked about
    on how order, complexity and chaos are emergent
    properties of a system

19
Immunoinformatics
  • We focused on epitopes know what they are and
    how they are processed by the immune system

20
Cheminformatics
  • How does one go about designing molecules to
    interact with proteins?

21
Theme Area 4
  • Systems Biology

22
Biological Pathways Network Motifs
  • What is a network motif and how are they found?
  • Why do some motifs predominate (e.g. the FFL
    motif)?
  • Alon paper

23
Artificial Life
  • What is AL and why do we fiddle with such things
    that arent real?
  • How does AL work in a general sense?
  • What is evolutionary computing (e.g. genetic
    algorithms) and how does it work?
  • Artificial life paper (Kim Cho)

24
Text Mining
  • Why mine text? What sort of things in it and why
    bother extracting them?
  • How can text mining be used to analyze
    microarrays or discover new knowledge?
  • Bork Nature Reviews paper

25
Cellular Simulations
  • What strategies are used to simulate cellular
    models and where is the current state of the art?
  • What is the range of modeling techniques, from
    the quantum level to the static level and what
    are their advantages/disadvantages?
  • IEEE paper

26
Systems Biology
  • What is SB and what is the strategy being used to
    try and model systems?
  • How can we begin to deal with the complexity in
    biological systems and the differences in time
    scale?
  • What are the features that define complex
    systems?
  • Nature SB paper

27
Synthetic Biology
  • How is SynthBio different from genetic
    engineering?
  • What is the strategy people are taking to attempt
    SynthBio?
  • What are the problems and limitations in
    SynthBio?
  • Bioinformatics review paper

28
Feedback
  • How was the workload compared to other classes?
  • Were there any areas you felt were over- or
    underemphasized?
  • What was the most interesting lecture/series, in
    your opinion?
  • What was the most boring lecture/series, in your
    opinion?

29
Feedback
  • How much of the material we covered do you feel
    will (or might) be useful to your own research or
    career interests in the future?
  • One of my goals was to have more breadth than
    depth in this introductory class do you think
    more depth would be better in the future?
